If you can build Git from source and have access to a debugger like gdb, that should be enough. One option is to make sure core dumps are enabled (probably "ulimit -c unlimited"), then run the failing repack, then find the core file (usually in the current directory, but I'm not sure offhand about macOS), and then open the debugger on it ("gdb /path/to/your/git /path/to/core"). But perhaps easier may be to directly run the buggy pack-objects invocation. I pulled the options here from your trace file. Something like: gdb -ex 'set args pack-objects \ --delta-base-offset tmp-pack \ --keep-true-parents --honor-pack-keep --non-empty \ --all --reflog --indexed-objects --unpacked --incremental \
