Microsoft Visual Studio C run-Time library detected an error in Xx.exe

Many times before this problem, and then after the resolution will appear on the forgotten how to do, this time record.

I've had this kind of error several times because of the qstring to const char* in Qt. My approach is to have a function tostring () to std::string

1 std::string  myprocessobject::tostring (QString strraw)2{3     return std::string((constChar *) strraw.tolocal8bit ()); 4 }

ToString ()

This is done because there are sometimes Chinese path problems.

And then every time I need to pass in the const char*, I'm ToString (QString). C_STR (), so that the direct parameter error occurs. The workaround is to:

String str=tostring (QString);

Then the incoming STR.C_STR () is available, the specific reason is unclear.
