Segmentation fault in git cherry-pick

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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)
