Mac executable bundled with Qt libraries crashes every time on start

Any simple application with main window (including the qt mainwindow sample) crashes after it's bundled with QT libraries using the following command:
/usr/local/Trolltech/Qt-4.8.0/bin/macdeployqt <app_name> -no-plugins -verbose=0

I'm talking about release build, of cause.

The callstack is always the same:

Exception Type: EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000

9 com.mycompany.myapp 0x0000850c start + 40

But if I delete the folder 'usr/local/Trolltech/Qt-4.8.0' from this mac machine, it runs OK. I believe it's some sort of confusion with libraries. It never happened with Qt 4.7.2 (used before on the same machine and same options)
