_DebugHeapDelete Access Violation at termination

I\'m getting a weird access violation at the end of my main whose cause I\'m having some difficulties finding.

When shutting down my application I get an access violatio

If you override the operator new and use you may meet the same cause as me. the code may be like

#include "yournew" //override new declare .. 
#include "fstream" 
std::fstream f
f.open(...)

because the iostream is template so the new of _Fac_node use your operator new. but when exit, your memory pool may exit before _Fac_tidy, then when ~_Fac_tidy() run,the program crashed.
