I’ll try gathering some more info

After removing all cache data the crash does not occur anymore :slight_smile:

cd "~/Library/Application Support/Sublime Text 3"
rm -rf Index Backup Cache
rm Local/Session.sublime_session

Looks fairly similar to https://github.com/sublimehq/Packages/issues/1671, I wonder if they are related somehow.

UPDATE

I can confirm that starting with env GDK_BACKEND=x11 subl as described in Issue #2488 fixes the problem.

Build 3181 segfaults on Linux too.

I’ve removed the entire .config/sublime-text-3 folder.

When I start subl, it asks me for the license. I enter my license, it says thank you, and on next start it segfaults.

dmesg output:

[  644.733751] sublime_text[3793]: segfault at 0 ip 0000000000000000 sp 00007ffe65b90678 error 14 in sublime_text[200000+2b2000]
[  644.733758] Code: Bad RIP value.

I’ve added valgrind output below, and the dump is here: https://transfer.sh/JTZGE/44352914-17fc-4d4e-44289288-dd663e51.dmp
