I checked using gb.gui.qt and it worked without crash. Great.
But then I turned jit-compilation on again (which I disabled for testing).
Bang! I got a segmentation fault.
So: yes, qt helps, but I think there is still something fishy here...
I attached the project with qt and jit enabled.
Note that for me it's the 'Fast' on WindowList::Merge() that triggers
the segfault. Remove that Fast and no crash happens.
?Puzzled?
