ArchLinux used to ship a Qt4 compiled without support for exceptions years 
ago, but I remember this caused trouble for me at the time (so can cause for 
other ISV as well) when I was using the QUndoCommand related classes and my 
classes inherited from QUndoCommand could throw exceptions on 
QUndoCommand::redo() if the command fail to execute, so the exception was 
throw by my application code when running Qt code (QUndoStack::push) and 
caused a nice segfault until the packager re-compile the Qt4 package with 
support for exceptions.
