This occurred with both Development and DebugGame build configurations.
In the game's console I tried both "quit" and "exit" and reproed the crash. The crash also occurs via Alt + F4 or closing via the 'X' in the game window.
I attached GDB to the process and the Core dump file and attaching them to the Jira. My log is from the DebugGame build.
Repro:
Result:
Game freezes for a second, then a crash is observed in the terminal after the game window closes.
Frequency:
100%
Program terminated with signal SIGSEGV, Segmentation fault.
