Description Real Name 2020-09-29 20:12:17 UTC
Created attachment 1717633 [details]
include QPainterPath for Qt 5.15

Description of problem:
TexWorks segfaults at start due to it being built with LTO enabled. Rebuilding it from source package fails because it's not fully compatible with Qt 5.15.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install package
2. Try to run TexWorks
3. It doesn't start, ABRT intercepts the crash

Actual results:
TexWorks segfaults at start

Expected results:
TexWorks should start normally

Additional info:
Attaching a simple patch to make it build with Qt 5.15 (not fully tested though), not addressing the warnings for now. Must also %define _lto_cflags %{nil} in the spec file.
