tilix freezes, crashes and uses 100% memory when a tile is closed

[Leonardo Müller]

Tilix is behaving in problematic ways when a tile is closed, differing with how the way tilix is closed. Sometimes all tiles will crash, sometimes the tilix windows will freeze and sometimes tilix will use 4 GB memory per closed tile. The memory seem to be recoverable after all tilix windows are closed.

I suspect this crash is similar to the bug 1950470, but I'm not sure.

What happens when I right click and choose close to close one tile is:

core.exception.OutOfMemoryError@core/exception.d(647): Memory allocation failed

[Thread 0x7ffff134f640 (LWP 8651) exited]
[Inferior 1 (process 8646) exited with code 01]

The last message before the crash and the backtrace I was able to get when closing with Ctrl+D are:

terminate called without an active exception
