Application: kdeinit5 (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-38-generic x86_64
Distribution: Linux Mint 18.3 Sylvia

-- Information about the crash:
- What I was doing when the application crashed:
I was testing ocmal code for a school project, nothing that would modify system memory. When testing, kwin crashes and just my konsole windows crash. All other windows stay open. Once kwin crashes initially, crashes become more frequent until a shutdown becomes necessary

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
