Debug runs but release crashes on launch

jelemans

Hi,
I am a new Qt developer. I have started with a simple app which runs fine in the debug build, but which crashes on launch in the release build. When I comment out code, the release works until I execute;

this->ui->setupUi(this);

It hangs in some Qt initialization, but only in the release build!

Any suggestions greatly appreciated.

Past more code. In debug uninitialized variables could have a different values then in release build, so it's important to have a initialized all variables.

I had the same trouble.
Sometimes the debug mode misses some exception messages.

Choose Build-> Clear All
Run QMake
Build all

If this fails, check out step by step, each line in debug mode, you will surely find it.
