This one has me scratching my head:

The object file name being reported below in t1450, subtest 2 is corrupt,
but I can't figure out why the script might be generating this condition -
there's nothing apparent, but it looks like the git commit -m C step is
reporting or using a bad name. This breakage was not present in 2.8.5 (now
at 7234152 (2.13.5) and is persistent (i.e. always happens). This is the
only test in all of git where I have observed this particular situation.
Adding set -x to test_commit is unrevealing. The git fsck in this test is
never executed because the test_commit fails with a non-zero git commit
completion code. There is no rn---- (actual r n 252 252 252 252) in the
objects directory - even the 'rn' does not correspond to anything.. I am
suspecting an unterminated string that ran into freed memory somewhere, but
that's speculative. 

Does anyone have a perspective on this - was it subsequently fixed?

Thanks,
Randall
