Qstring toStdString() and Multi-threaded DLL (/MD)

[Daxos]

Hi,
i have this problem:
I'm working on visual studio 2005 on Windows. I have compile qt source whit the standard command "configure" whitout any parameter.
On my application i would using the function to convert a Qstring to a std:string:

QString test = "Test";
std::string  converted = test.toStdString();

QString test = "Test";
std::string  converted = test.toStdString();

To copy to clipboard, switch view to plain text mode 

This code work correctly if my project configuration is Multi-threaded Debug DLL (MDd) but the problem is that my application must be an Multi-threaded DLL (/MD) application but whit this configuration this code don't work correctly: i receive a null pointer.


Can anyone help me please??
