Why are you casting setSrvDir to char *? If its not already a character pointer, might it be unicode? or some other thing? This may be a non-issue, but it raises small alarms...

I came across a utillity from the net that does just that, but I need the code so that the same thing can be done from our application.

I'd guess you've corrupted the heap at another location in your program and the problem in manifesting here. Try the following:

CSomeClass::~CSomeClass()<br />
{<br />
m_oApplicationConfig.clear();<br />
<br />
return;<br />
}

CSomeClass::~CSomeClass()<br />
{<br />
m_strConfigFileName.~basic_string(); << Crashed here! <br />

Now:

CSomeClass::~CSomeClass()
{
m_oApplicationConfig.clear();

return;
}
