Description Jan-Matthias Braun 2020-05-11 15:48:31 UTC

Application: kdevelop (5.5.1)

Qt Version: 5.15.0
Frameworks Version: 5.70.0
Operating System: Linux 5.6.11 x86_64
Windowing system: X11
Distribution: "Gentoo Base System release 2.7"

-- Information about the crash:
- What I was doing when the application crashed:
I externally renamed a source file, updated CMakeLists.txt and then updated the project view.
The file chanced its name. I believe I have tried to open the file when kdevelop crashed.

-- Backtrace (Reduced):

I believe this is a bug within clang, as the crash points only to libclang - I doubt it's related to the fact that you reloaded something in the project view? Or can you reliably make it crash then? If so, can you attach a project to reproduce this with the exact steps required to trigger this issue?
