I can confirm that it crashes using 2.93 with the debug log showing:

There is an error reported when trying to load the symbols for the crash log.

However, it doesn't crash when using 3.0.0. The debug log just shows:

INFO: Could not find files for the given pattern(s).

@PratikPB2123 could you use your awesome triager powers to figure out which commit fixed this? We can then see if we can backport the fix to 2.93 LTS or not.

@dr.sybren hi, sure, I'll do :)
But bisecting will take time (I'll first need to grab old libs from server)
Crash appear to be fixed prior to 3.0.0 release

Ran git bisect between these hashes 1a81693d38 - 9dabb342ba, I found no build with the crash (used lite ninja build and r62588 lib version)

In the end git bisect points to 86915d04ee which is not the resolving commit I think

In that case I'd consider this "fix" too vague to back-port to 2.93 LTS. Thanks for your efforts!
