I have a non-bare repository /home/a set up with an alternate to the bare repository /b. Running git gc on /home/a produces below's error

error: unable to open
/b/objects/56/b969ffdf64343777a069260f41761dc0551bfa/00: Not a directory

The referenced file

/b/objects/56/b969ffdf64343777a069260f41761dc0551bfa

exists, but is not a directory.

Thanks,
- Eph

Try v2.3.2. It has b0a4264 (sha1_file: fix iterating loose alternate objects, 2015-02-08), which is almost certainly the problem.

Indeed, the message is gone in v2.3.3. Thanks!
