I just tried to compile the Suse Linux package libQtWebKit-devel-4.4.0-11 with the new gcc version 4.4, snapshot dated 20080926.
gcc said puzzlewidget.cpp: In member function 'virtual void PuzzleWidget::mousePressEvent(Q MouseEvent*)': puzzlewidget.cpp:143: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
