Description jussi.kuokkanen98 2020-06-11 16:30:16 UTC

Application: kdevelop (5.4.2)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-55-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
I had the background parser on C++17 mode, and KDevelop crashed when it came across a structured binding (auto [x, y] = z;)

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
