Bug 424762

Application: kdevelop (5.5.2)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.7.0-2-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

-- Information about the crash:
- What I was doing when the application crashed:

Editing C++ source code. This has happened several times already. It seems like it happens when I edit and kdevelop is checking the syntax concurrently.

The crash can be reproduced sometimes.

-- Backtrace (Reduced):
