Sublime Text 4 is going segfault when switch branches on git (Sublime Text 3 didn't)

Description of the bug

Sometimes when I change branches in a large repository, Sublime Text just segfault.

Until last week I was using the latest build of Sublime Text 3 and never had this issue when switching branches in my projects.

I found this on my /var/log/syslog (today was not the first time after updating to Sublime Text 4)

Are there any core dumps I can upload? Where they would be? I think core dump is enabled on my system:

$ ulimit -a

Steps to reproduce

I have some Sublime Text windows open in some thousands of files and switch branches in one of my repositories.

Expected behavior

Do not segfault when switching branches.

Actual behavior

We get crash reports automatically, I believe that system intercepts normally generated core dumps.

You could get a traceback/coredump using gdb subl --multiinstance --debug, followed by r. Once it crashes you can type bt to get a backtrace or generate-core-file to get a core dump.
