I am running Matlab from a Fortran function and am having a persistent problem that I am getting the error
*** glibc detected *** /matlab/8.5/bin/glnxa64/MATLAB: double free or corruption (out): 0x00002b11a9a86f20 ***
I am not sure which line the error is occuring on but I have quite a few that follow this pattern
MLVar = engGetVariable(ep, 'un')
call mxCopyPtrToReal8(mxGetPr(MLVar), SurfaceField, BoundaryCells)
call mxDestroyArray(MLVar)
and I go through this function between 1 and 100s of times before this error occurs.
It looks like here they said to use mxDestroyArray which I'm already using.
Any advise?
The problem ended up being completely unrelated. I am submitting this to a remote cluster using a submission script, and I used a "V" option and then when I closed my terminal connection with Matlab forced close.

[ script:es_extended] SCRIPT ERROR: #es_extended/server/functions.lua:127: attempt to index a nil value (local 'xPlayer')
[ script:es_extended] > ref (#es_extended/server/functions.lua:127)
Please help me im triggered af Thats my Fivem Console (TxAdmin) Nothing works Esx is completly broke after a server Restart
I had a look at the source code. My best guess is that the player you are using isn't registered in the MySQL database for some reason.
I am guessing this because of the following:
The immediate cause of the error is that xPlayer is nil in server/functions.lua:127
This is due to the player object not being added to the ESX.Players table in server/main.lua:239
The info necessary to make the player object is taken from MySQL on server/main.lua:115
So the most obvious explanation would be that the user wasn't found in the database. It is also possible that the program could not connect to the database at all, but it looks like the fivem-mysql-async library would raise an error instead of continuing silently, so that is less likely (although this would need testing to discount completely).
Are there any messages in the server logs that might give you a clue as to what's going on?
I am running the following MATLAB code on a system with one GTX 1080 and a K80 (with 2 GPUs)
delete(gcp('nocreate'));
parpool('local',2);
spmd
gpuDevice(labindex+1)
end
reset(gpuDevice(2))
reset(gpuDevice(3))
parfor i=1:100
SingleGPUMatlabCode(i);
end
The code runs for around a second. When I rerun the code after few seconds. I get the message:
Error using parallel.gpu.CUDADevice/reset
An unexpected error occurred during CUDA execution. The
CUDA error was:
unknown error
Error in CreateDictionary
reset(gpuDevice(2))
I tried increasing TdrDelay, but it did not help.
Something in your GPU code is causing an error on the device. Because the code is running asynchronously, this error is not picked up until the next synchronisation point, which is when you run the code again. I would need to see the contents of SingleGPUMatlabCode to know what that error might be. Perhaps there's an allocation failure or an out of bounds access. Errors that aren't correctly handled will get converted to 'unknown error' at the next CUDA operation.
Try adding wait(gpuDevice) inside the loop to identify when the error is occurring.
If either device 2 or 3 are the GTX1080, you may have discovered an issue with MATLAB's restricted support for the Pascal architecture. See https://www.mathworks.com/matlabcentral/answers/309235-can-i-use-my-nvidia-pascal-architecture-gpu-with-matlab-for-gpu-computing
If this is caused by the Windows timeout, you would see a several second screen blackout.
I am using ispin and got an error stating spin: trails end after 10 steps and transition fail.
How can I prevent this error from happening?
You prevent the error from happening in one of two ways:
fix your Promela model - you have a bug in your Promela that needs to be removed
you've found an error in the system that you are modeling. Congratulations. You now report the error to the person in charge of the system that you are modeling.
In practice, when you have a trail indicating an error, you next perform
spin -p -t <name of the model>.pml
which will print out the step by step model executions that lead to the error. You scour them to confirm that they are correct - if so, see #2 above; if not correct, see #1.
I had the same problem and it is fixed after putting -DVECTORSZ :
in the advanced parameters settings window of verification tab.I have also increased the physical memory to 2048.
When I create a new quote from Epicor I would like to add an item from the parts form automatically.
I am trying to do this using the following ABL code which runs when 'GetNewQuoteHed' is called:
run Update.
run GetNewQuoteDtl.
run ChangePartNumMaster("Rod Tube").
ttQuoteDtl.OrderQty = 5.
run Update.
I am getting the error:
Index -1 is either negative or above rows count.
This error occurs for each line in my ABL code.
What am I doing wrong?
That's not the proper format for a 4GL error message (nor is it at all familiar) so I'd say it is an Epicor application message. Epicor support is probably your best bet. However... Just guessing but it sounds like you might need to somehow initialize the thing that you're updating.
Agree with #Tom, but i would also say try and isolate the error and see where the error is raised as soon as you find the point the error is actually raised it is normally much easier to figure out exactly what is going wrong and how to solve it.
Working between a 0 based and a 1 based system there can be issues with the 1st or last entry depending on which way you moving. As the index for 0 based systems starts at 0 and ends at n-1 where 1 based systems start at 1 and end at n.
I'm testing my app on simulator 3.1.3, it runs fine.
When it come to simulator 3.2, it crashes right from the beginning:

As far as I know, I do not use the "initWithCoder" method (do not really know what this is though).
How can I know where the exception is thrown so I could have a better understanding of what is causing the problem?
ps: I have added an exception in Breakpoint: objc_exception_throw (with location libobjc.A.dylib, strangely I had to enter the location manually, I expected xcode to find it for me when I added objc_exception_throw). But still the same trace and no more information.
This page should provide some helpful info: Debugging Tips for Objective-C
Of particular interest is the console command info line *. Every one of those numbers listed by the exception log is an address on the stack. Those bottom ones in the 10,000 and below range are usually located in the app's main method, for example. The highest ranged addresses tend to represent the default libraries.
Using the command info line *10678 would likely return some info about a specific line in the main method, which doesn't help very much. Normally the trick is to find the highest address before the default libraries begin. I'm unsure how much this will help your problem in particular, seeing as there's a huge gap between the expected small addresses and the next highest up. In any case, start with the smallest address above the bottom two (3555255 from what I can see in the log you posted) and see if it returns a line from one of your own code files. If it does, check the one above it, and so on until you find the last address from your own code. Hope this helps.
I figured out the reason of this error. I had created an object of type NSDictionnary within IB and it seems it was not the correct way to do this. Instead I have programmatically created this same object in XCode and this works fine. Seems like it was some kind of persistent problem.
