CDB crashes in Qt project

The riddle I am going to present to you just blowing my mind. There is a project written on Qt 4.8.2, compiled by MSVC 2010 compiler, 32-bit application. It uses lapack linear algebra library and also some networking to download and present Google maps to the user. I'm not the author of the code: the author gave me source code as well as compiled application and my task is to adapt it to my purposes.

The application doesn't run on my Windows 7 Ultimate x64 system. More specifically, it runs but then hangs up showing no GUI, consuming 25% of CPU (i.e. one core) and the only way I can kill it is through Task Manager.

When I compile it in Qt Creator with MSVC2010 compiler and run under CDB - it crashes; the debugger's listing is presented below.

What is more - the application runs smmothly on my colleagues' computers as well as in the same Win7 system in the Virtual box. In client system the application runs but in the host system it hangs up! Re-installing the Win7 system didn't help: on the completely new system the situation repeated exactly.

Simple test application (doing nothing - just showing up a simple window) is being compiled and runs smoothly. The problem is only with that 'problem' application.

What could be done about this? How can I make application work? I've run out of ideas. Because the Win7 system is clean - there are no Qt dlls in the Windows/System32 folder - nothing to delete.
