Hi
i have problems with big projects (for example Natron). The crash happens due to memory corruption.
Version is Qt Creator 4.13.1 based on Qt 5.15.0, 
Uname - FreeBSD  12.1-RELEASE-p10 FreeBSD 12.1-RELEASE-p10 GENERIC  amd64
Here is gdb backtrace

Comment 4 Adriaan de Groot freebsd_committer freebsd_triage 2021-04-23 11:06:38 UTC 
Have you tried a more recent QtCreator? There have been two updates since 4.13.1.

Moreover, we need a lot more information in order to try anything. Please write out a scenario for someone who **doesn't use Qt Creator at all** what to do to trigger the problem. I've run qtcreator twice in the past 12 monhts -- because of this PR, just today -- and all I can say is "it starts, and seems to be able to load something from the example projects in  /usr/local/share/examples/qt5/widgets/graphicsview/anchorlayout".

(Three times by now, since `qtcreator .` seems to be able to handle CMake-based projects, and it managed to build calamares for me -- no crashes or anything, so you'll need to point to more specific actions)
Comment 5 Adriaan de Groot freebsd_committer freebsd_triage 2021-05-31 18:20:03 UTC 
Closing as "can't reproduce / feedback timeout"; it seems to be ok for me, and unless I get a scenario that reliably demonstrates the problem, there's not much I can do.
