Re: Adding member variables crashes app

CIDriver, CDriver and CMyDriver all have virtual
destructors.

__declspec(dllexport) CIDriver* InitDriver(CIKernel*
i_hKernel)
{
 //__asm { int 0x03 }

 CMyDriver* hUserDriver = new CUserDriver;
 hUserDriver->Create(i_hKernel);
 return (CIDriver *)hUserDriver;
}
__declspec(dllexport) void EndDriver(CIDriver* i_hIDriver)
{
 CMyDriver * hUserDriver = (CMyDriver *)i_hIDriver;
 hUserDriver->Destroy();
 delete hUserDriver;
}

My app crashes at the 'delete hUserDriver'. EndDriver is
an exposed
interface call that another DLL calls to detroy the
driver.
hUserDriver->Destroy() destroy all internal structures of
CDriver (not
CMyDriver, as this function isnt overloaded in CMyDriver).
CMyDriver is not
referencing any objects destroyed by the Destroy call.
Nothing is available
in the debugger as its all assembly at that point.

In the class definition for CMyDriver, if I add public
member variables, it
crashes on the delete. If I make them global (file scope),
it doesnt crash.

I"m wondering if its looking at the class size or
something. I'm just
confused.

I'd add the code snippet, but I'm not doing anything
special that would look
weird.
