Bugreport: pack-objects died of signal 11

["Paul Horn" <git@knutwalker.engineer>]

Hi,

ultimately, `git repack` segfaults:

    $ git repack
    error: pack-objects died of signal 11

This also errors out GC runs and breaks index maintenance, though other commands still succeed.

    $ cat $(git rev-parse --git-dir)/gc.log
    error: pack-objects died of signal 11
    fatal: failed to run repack


The repository is a bare repository with 11 worktrees. I can only observe this error in this repository, others do not reproduce it.
The attached log contains the output of `GIT_TRACE=1 GIT_TRACE_PACK_ACCESS=1 git repack`
