Sentry Crash Report:
Attachments:	The file to reproduce the clang and therefore the kdevelop-crash

Description Anton Kreuzkamp 2018-04-29 15:46:54 UTC

Application: kdevelop (5.2.1)

Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
KDevelop parsed a file that causes clang to crash. The stack trace suggests that KDevelop tries to recover from the crash (the KDevelop-crash happens inside a llvm::CrashRecoveryContext), but fails to do so.

For a file to reproduce the crash see attachment. I have clang 6.0.0 installed.

The crash can be reproduced every time.

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

Created attachment 112306 [details]
The file to reproduce the clang and therefore the kdevelop-crash

It's already enough to open the file without a project.

Comment 2 Sven Brauch 2018-04-29 20:24:18 UTC

Assuming the decision that libclang runs in-process, there is not really anything KDevelop can do about this ... the CrashRecovery stuff is from libclang itself. The reason for the crash needs to be fixed upstream.
