OpenSC Program Crash with c0000005 on Windows - pkcs#11

Question

All, I am trying to access opensc dll(latest version) on windows 7 64 bit. I am trying to access a ePass2003 token. The opensc-tool is able to detect the token and can get name and other information. So the token is found by OpenSC. Then I am loading the opensc dll from another program and call standard PKCS#11 functions. C_GetSlotList is returning slot 0 ID as -1 and slot 1 ID as 1. The C_GetFunctionList is returning me pointers to functions. The problem is when I call C_GetMechanismList I am getting a crash with c0000005 error.
I also have accessed the token through the ePass dll provided with the token, it works perfectly.
I am unable to track this problem as it is looking like through the opensc dll, opensc is unable to interface with the card but then opensc-tool also should have the same problem but it does not.
If someone can help it would be great.

OpenSC PKCS#11 library sees your token as "uninitialized". If I remember correctly ePass token initialized with Feitian middleware cannot be used with OpenSC, and vice versa. So if you want to use ePass with opensc-pkcs11.dll then you will need to use pkcs15-init.exe application shipped with OpenSC to initialize your token.
Documentation references:
OpenSC wiki mentions requirement for reinitialization on ePass3000 page but not on ePass2003 page. European distributor gooze.eu also states that reinitialization is required:
The reason is that the ePass2003 is pre-initialized to be recognised
under Windows7 by Feitian priprietary software. To be usable, the
ePass2003 need to be initialized by OpenSC.
Practical examples:
I have initialized my ePass2003 token with Feitian middleware and tested with proprietary eps2003csp11.dll library - it was working fine:
C:\Program Files (x86)\OpenSC Project\OpenSC\tools>pkcs11-tool.exe --module eps2003csp11.dll -M
Using slot 0 with a present token (0x1)

Then I have tested with opensc-pkcs11.dll and got the same crash you are describing:
C:\Program Files (x86)\OpenSC Project\OpenSC\tools>pkcs11-tool.exe --module opensc-pkcs11.dll -M
Using slot 1 with a present token (0x1)
So I have erased the card..
C:\Program Files (x86)\OpenSC Project\OpenSC\tools>pkcs15-init.exe --erase-card
Using reader with a card: FS USB Token 0
..initialized with OpenSC pkcs15-init application..
C:\Program Files (x86)\OpenSC Project\OpenSC\tools>pkcs15-init.exe --create-pkcs15 --profile pkcs15+onepin --use-default-transport-key --pin 0000 --puk 111111 --label "ePass2003"

However eps2003csp11.dll distributed by Feitian stopped working as expected:
C:\Program Files (x86)\OpenSC Project\OpenSC\tools>pkcs11-tool.exe --module eps2003csp11.dll -M
No slot with a token was found.
