Application: kdevelop (5.13.231170 (23.11.70))

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-13-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
Recently seen repeated crashes while editing code. Every few hours. 
In the last week or two, have seen the top crash trace entries seem to been dealing with an atomic value whenever I looked at the trace. I'm guessing it is the same error.
compiled from git master on clang-16 on debian stable. 
Happy to supply any info or do any tests, as I love kdevelop.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
