Im getting an access violation from opengl32.dll in my application. My application uses OpenGL for drawing some objects(texture mapping)to screen in 60 fps.
On main draw thread, opengl rendering context is created and it will perform all opengl operations. No other threads are calling opengl functions.
When the issue occurs, we create crash dump of the process. On analysis of crash dump, opengl thread is in wait state[rendering is in pause mode]
therefore the access vioaltion is not occured from my opengl drawing thread. But the callstack says the last symbols are opengl32!__safe_se_handler_table.

I suspect there are some internal threads in opengl creating this issue.
Is there any chance to have internal threads for opengl operations.
I'm getting this issue after 2 hours of testing of my application.
I tried 2000 times to reproduce this issue, but it reproduced twice.
I cant identify any reason for this issue.

Any indication to identify the reason is most helpful for me.
I cant proove this issue is not related to my opengl operations.

Is there any chance to get access violation from internal thread if i perform somthing bad in main opengl thread ?

Please check the CallStack of access violation thread.
