Problem document
I can reproduce it at will. The CLI shows me: Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there. terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc I fear this is a Sonnet or even Qt bug, but I'm not sure... I've narrowed the test case down to $A'' \test$ and it only crashes if LaTeX highlighting is enabled. I think I know where the problem could be... Created attachment 40616 [details]
