I'm using the default configuration of g++-multilib (g++-5-multilib) from
experimental (e.g. $ sudo apt-get -t experimental install g++-5-multilib g++-
multilib).
I'm using Qt5 libs from experimental (install qt5base-dev).
I tried different scenarios, I used qt/examples/widgets/mainwindows/application
example and I also tried QtCreator ($ git clone git://code.qt.io/qt-
creator/qt-creator.git).
I compiled them without any special settings regarding [libstd]C++ standard ($
qmake -r CONFIG+=debug; make -j10).
When I'm trying to run them, they crash immediately.
It seems related to https://bugreports.qt.io/browse/QTBUG-45755, it has almost
the same call stack when it crashes.
