What does "dynamic" in "dynamic atexit destructor" mean?

Question

I ported my application from VC++7 to VC++9 recently. Now it sometimes crashes at exit - the runtime starts calling global objects destructors and an access violation occurs in one of them.

Whenever I observer the call stack the top functions are:

CMyClass::~CMyClass() <- crashes here
dynamic atexit destructor for 'ObjectName'
_CRT_INIT()
some more runtime-related functions follow

The question is what is the meaning of the word "dynamic" in "dynamic atexit destructor"? Can it provide any additional information to me?

Answer 1

its difficult to pinpoint the exact problem without the actual code, but maybe you can find it yourself after reading this
