Crash on exiting QGIS master

[qgib]

Author Name: Andreas Neumann (@andreasneumann)
Original Redmine Issue: 20211
Affected QGIS version: 3.3(master)
Redmine category:unknown

---

I am experiencing crashes when closing QGIS with the most recent master:

When I open QGIS (no plugins enabled, completely empty and new profile), and I do nothing (not even a simple project opened).

I close QGIS and it crashes on closing.

Am I the only one experiencing such crashes on closing?

System: Linux Ubuntu 18.04.1 LTS

QGIS: most recent master, self-compiled.

Maybe an issue only on my machine?

Seems like valgrind stopped outputting information.

Should I run it again with --error-limit=no ?

Perhaps the necessary information is now cut off ...

I'm experiencing such crashes on exist for several months now. I've never inspected it further, but I think a plugin is the reason. It didn't crash on a fresh installation, but after adding all my standard plugins, it crashed again. Windows 7/10

The log is useful, but can't really explain why such errors would occur. Hum, when I had similar errors in the past, it was due to having several versions of native providers / plugins from the current version and past version. But normally we have modified things so that this should no longer occur. But just in case can you try removing completely /usr/local/lib/qgis and removing all /usr/local/lib/libqgis* files, and "sudo make install" again .

This did it. You were right. Old versions of qgis libraries around 2.99 and such.

After removing everything and reinstalling, the crash is gone.

Thanks a lot!
