Comment 1 edpil02 2020-08-25 05:13:58 UTC

Same issues with the latest fedora 33 live kde compose.

Comment 2 edpil02 2020-08-25 12:47:05 UTC

The crashes seems  to came from the  LTO flags build.

Adding  " %define _lto_cflags %{nil}"  in the spec file and rebuild the package solves the issue.

Comment 3 Guido Aulisi 2020-08-25 14:30:00 UTC

Latest rawhide build is without LTO (https://koji.fedoraproject.org/koji/taskinfo?taskID=50140186).

Can you try with that?

Comment 4 edpil02 2020-08-25 14:41:57 UTC

Your build is ok.
The bug is resolved.

Thanks
