git-fetch segfault in git 1.5.5.1

Since master.kernel.org updated to latest, I noticed that I could crash
git-fetch by doing this..

export KERNEL=/pub/scm/linux/kernel/git/
git fetch $KERNEL/torvalds/linux-2.6 master:linus

(gdb) bt
#0  0x000000349fd6d44b in free () from /lib64/libc.so.6

#7  0x00007fffea4449d8 in ?? ()
#8  0x0000000000000000 in ?? ()

I then remembered, my .bashrc has this..

export MALLOC_PERTURB_=$(($RANDOM % 255 + 1))

which is handy for showing up such bugs.

More info on this glibc feature is at http://udrepper.livejournal.com/11429.html
