Question

I am working on a Win32 c++ application in Visual studio.

In one of the source files, I have global object like below.

TestClass tObj;

int main() //Execution starts here
{
}

TestClass is defined in other DLL like below.

struct Source
{

};

class TestClass
{
  list<Source> sourceList;
    public:
         TestClass() {}
        ~TestClass() {}
};

While my application is running, if i try to close the app explicitly,
by closing the console window, it is crashing in TestClass destructor.
Callstack shows CrtIsValidHeapPointer is failing.

Pls help me to solve this issue.

Make sure you build bot the EXE and the DLL with the same runtime, preferably with the dynamic runtime.
