this might be a bug in the qt library version 5.15.2+kde294-5.2 from the OpenSuse tumbleweed repository, but I don't know.
I have a project which is heavily configurable via a spreadsheet. For now I found two parameters which altered will crash FreeCAD. At least most of the time. Astonishingly while I tried to get the second backtrace it one time worked and just produced this output:
Code: Select all
QObject::installEventFilter(): Cannot filter events for objects in a different thread.1. one:
Code: Select all
Thread 1 "FreeCAD" received signal SIGBUS, Bus error.
