[Qt-interest] program crashes for Qt lib built with MinGW 5.1.6

[AdityaShirolkar at Eaton.com]

Hi,

I built qt library from source code
(qt-everywhere-opensource-src-4.7.1.tar.gz) using MinGW 5.1.6 and MSYS
1.0.14-1 on windows xp.
It compiles without errors.

I tried to run a sample application from one of tutorial websites.
It compiles but when I try to launch the exe file, it crashes.
I also tried to execute the examples in qt sources, same behaviour.

Is there a dependency of qt lib on the compiler version used to compile
it?
I found a thread which had similar problem to mine:
http://lists.qt.nokia.com/pipermail/qt-creator/2010-April/006648.html
but it does not offer a solution :(

I don't want to install multiple versions of a compiler. Any ideas?


Following is the backtrace:
