[Octave-bug-tracker] [bug #40498] opening or saving files crashes the GUI on OSX

[Torsten]

Follow-up Comment #1, bug #40498 (project octave):

Here some mor informations:

The crash happens with QSintilla versions 2.6 or higher.

Attached a patch that strips most of the configurations of edit_area (the
qscintilla editor). The remaining steps when loading an existing file related
to _edit_area are:

+verbatim
_edit_area = new QsciScintilla;             // in constructor

_edit_area->setText (in.readAll ());        // in load_file

QsciLexer *lexer = _edit_area->lexer ();    // in update_lexer
delete lexer;
lexer = 0;
//...  determine lexer from file extension
_edit_area->setLexer (lexer);   // ---> crash

  
A minimal example with those steps does not crash.
