[Octave-bug-tracker] [bug #50210] octave-gui crashes on exit

[anonymous]

Follow-up Comment #2, bug #50210 (project octave):

This issue occurs with Qt 5.8.0 because the error message

_QThread: Destroyed while thread is still running_

is now emitted by qFail() instead of qWarning(). It means that now Qt issues a
SIGABRT that is caught by octave.

The following patch works for me:


--- origsrc/octave-4.2.0/libgui/src/octave-qt-link.cc
+++ src/octave-4.2.0/libgui/src/octave-qt-link.cc
