Memory leak std::wstring L" "

[schliz]

I have a global variable in a cpp file, in this file there is the
implementation of a class. At the constructor, I set the example
variable to " ".

global variable in the same file:

####### file.cpp

std::wstring szVar;

in a constructor of a class in this file, I set this variable to " ":

CMyClass::CMyClass()
{
szVar = L" ";
}

###### file.cpp end


I get:
Detected memory leaks!
Dumping objects ->
{762} normal block at 0x039FAFE8, 16 bytes long.
Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD
CD

Thank you very much for your help.

The dump is clearly part of MFC which is OT here.
Never trust MFC when it tells memory leaks, it detects them too early.
In this case there is no leak as the static is not cleared before MFC
detection.

Are there any static instances of CMyClass anywhere. You may be
encountering an order of initialization problems. (Also, I'd
avoid starting a class name with a capital C, followed by a
capital. That convention is used by Microsoft, to indicate that
the class is part of MFC.)
