Try this out, in Visual C++ .NET 2003...
1. Create new ATL project.
2. Add new class, ATL ActiveX control.
3. Add "#include <atlutil.h>" to top of .h file of control
4. Add "CWorkerThread<> m_testThread;" member variable to control class.
5. Compile on Windows XP machine.
6. Copy over to Windows 98 machine.
7. Create the control in tstcon32.
8. Destroy the control.
WHAM -- you will get:
Just declaring the CWorkerThread member variable in your control will cause this to happen. You don't have to call any of its methods (besides the constructor/destructor called for you). Also, the crash only occurs on Windows 98. But it is consistent and very reproduceable. I can make it happen on Windows 98 SE and Windows 98 vanilla, both running the latest patches.
