Can you consistently reproduce this? Maybe Stefan can make some sense of
this, but it would be really useful if you could compile git from the
master branch with CFLAGS="-O0 -g" and run gdb with that and paste that
backtrace, and even better if you're in a position to share a copy of
the repository where this happens.
