Hrm. Can you try getting a backtrace from
$ gdb ~/projects/git.git/git-fsck
(gdb) run
... wait until it crashes ...
(gdb) backtrace full
I would have been more interested in error output from valgrind, because
memory corruption invariably happens long before glibc finally figures
out that something is amiss. But as things stand, the backtrace is
probably the only thing we have...
