SYMPTOMS
When you try to interrupt a running script thread with IActiveScript::InterruptScriptThread, you receive one of the following errors:

 caused an invalid page fault in module OLEAUT32.DLL at 0137:65347989

-or-

Access violation in OLEAUT32.DLL



CAUSE
The documentation for the IActiveScript::InterruptScriptThread method indicates that you should pass the address of an EXCEPINFO structure as the second parameter. However, it fails to mention that this structure must be initialized because InterruptScriptThread will try to use information stored in the EXCEPINFO structure.



RESOLUTION
To correct this problem, do one of the following two things:   Pass NULL for the second argument, pexcepinfo, of InterruptScriptThread. Here's an example: pActiveScript->InterruptScriptThread(SCRIPTTHREADID_BASE, NULL, 0);   Initialize the EXCEPINFO structure before passing it to InterruptScriptThread. Here's an example: EXCEPINFO ex; memset( &ex, 0, sizeof( EXCEPINFO ));

pActiveScript->InterruptScriptThread( SCRIPTTHREADID_BASE, &ex, 0 );
