Bug ID: 382334
Summary: freak crash through libllvm mismatch
Product: kdevelop
Version: git master
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
Running KDevelop remotely from my Linux rig I'm seeing the crash below.
Looks like a nasty one where for some reason libLLVM 3.8 gets loaded for a
reason outside of my control and then starts being used instead of the intended
library version which is clearly already loaded.
This may have something to do with it:
```
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
```
at least I hope so since otherwise I am apparently lucky that the same issue
doesn't bite me when I'm running locally...
What really strikes me is that the jump to libLLVM-3.8 happens in a function
from libLLVM-4.0 .
It seems possible to work around this by replacing libLLVM-3.8.so.1 with a
symlink to libLLVM-4.0.so.1 but a better solution would be preferable. The
issue does ring a bell for me, has anyone ever looked into it?
Program received signal SIGSEGV, Segmentation fault.
