_CrtIsValidHeapPointer crash in 64 bits

[EDN Admin]

Hi,
I have an application that seems to run correctly in 32 bits, but when I run it in 64 bits, when exiting the application Visual Studio 2010 is stopping at _CrtIsValidHeapPointer.
What is strange is that my application contains an empty main.

Here is the call stack at the exit :

Notice that I never create any std::locale object myself... I have put a breakpoint in the locale constructor and it seems that it is the CRT that create this object !

Does someone has an idea of the problem ?
