-- Information about the crash:
- What I was doing when the application crashed:
Accidently copied debug arguments with line break symbol and launched debugging
session. GDB replied with error:
The exception is: Received a result with token not matching pending command.
Pending: 23Received: 0
The MI response is: ^error,msg="Undefined command: \"_DIR\". Try \"help\"."
and then KDEvelop crashed.
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
