Description andras.vukics 2016-10-17 08:58:16 UTC

Application: kdevelop (5.0.1)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.7.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
KDevelop crashes immediately after opening a project (either from an existing .kdev4 file or from a CMakeLists.txt). It doesn’t seem to get to the point of loading the project (listing the files, etc.), but the window remains completely empty.

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".

=> You're getting a SIGSEGV in libclang. This isn't necessarily critical, libclang likely can recover from a SIGSEGV. You need to continue debugging in order to find out the real issue for crashing.

If GDB is paused, with a backtrace like this, enter the following:
  signal SIGSEGV
  continue

This will make GDB re-raise the signal and continue debugging

(Note you might have to re-enter those commands multiple times, in case KDevelop crashes again inside libclang.)

GDB output together with first pause – signal SIGSEGV – continue

I’ve done as you suggested, and I’m attaching the output of GDB

GDB output together with first pause – signal SIGSEGV – continue

Sorry, forgot to tell you: please also install debug symbols for libclang. 

Please generate a backtrace for both the first and the second SIGSEGV.

Sorry, but all the software I use comes from arch packages, and I couldn’t find the libclang debug symbols packaged for arch.
