A newer version (2.14.2 from Debian stretch-backports) fixes the
issue. I can now do my cherry-pick.
Thank you!

This looks like the stack trace in
https://github.com/git-for-windows/git/issues/952, which was fixed by
Johannes Schindelin in commit
55e9f0e5c ("merge-recursive: handle NULL in add_cacheinfo()

Segmentation fault in git cherry-pick

2018-01-31 Thread Ayke van Laethem
Hi all,

I've found a segmentation fault in git.

Here, fabsf is a branch that I'm trying to get the topmost commit from.
After the failed cherry-pick, the change is added to the local working
tree, but the commit isn't applied and .git/index.lock still exists.

Version: 2.11.0 (Debian stretch)
