I narrowed down one group of crashes.
revieviewing commit you have the bottons to jump to differences. Kdevelop crashes almost always when I click "next difference"
it was the same since 5.2 that I was using previously.
Comment 2 Sebastian Turzański 2020-06-29 13:23:45 UTC 
on 9600 code lines case the frequency of crashes is 95%
Comment 3 Justin Zobel 2022-10-12 03:49:45 UTC 
Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version?

If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!
