Hopefully this will be a simple question to answer.

I have a derived CWinThread class and in my InitInstance() I call some 3rd party library which appears to be crashing with an access violation in the function below:

Why is this occurring?

Thanks!


static void _callthreadstartex(void)

{

_ptiddata ptd; /* pointer to thread's _tiddata struct */

/* must always exist at this point */

ptd = _getptd();

/*

* Guard call to user code with a _try - _except statement to

* implement runtime errors and signal support

*/

__try {

_endthreadex (

( (unsigned (__CLR_OR_STD_CALL *)(void *))(((_ptiddata)ptd)->_initaddr) )

( ((_ptiddata)ptd)->_initarg ) ) ;

}

__except ( _XcptFilter(GetExceptionCode(), GetExceptionInformation()) )

{

/*

* Should never reach here

*/

_exit( GetExceptionCode() );

} /* end of _try - _except */

}
