Crash in ghostel__adjust_size_0 when Magit exits (Race condition in process filter)

[bommbo]

However, the crash is intermittent and I cannot reproduce it consistently. It seems to be a race condition that occurs when Magit (eg. gst)exits.

Fatal error 6: Aborted

Would it be possible for you to build the Zig module in Debug mode and try to make it happen? The stack trace is a bit useless without it unfortunately.
