Application: kdevelop (5.0.1)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.57-18.3-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
Reproducible crash of KDevelop when adding a doxygen's /*! \brief */-comment.

Likely that this behaviour is connected to the background code analysis.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
