Sentry Crash Report:

Description dhanav 2022-01-31 19:39:10 UTC 
Application: kdevelop (5.5.0)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.13.0-27-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Writing C code.

- Unusual behavior I noticed:
The background parser runs for a long time, but does not go beyond 24%. This is a fairly large project that includes C (project sources) and C++ files (boost libraries, cloud SDKs, etc). The kdevelop application is taking 200% - 400% CPU and a large RSS memory. The background parser has been configured to use max 4 threads and wakeup every 1 second.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
