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 #1 0x000000000048f4eb in transport_unlock_pack (transport=0x7ce530) at transport.c:811 #2 0x000000349fd31b25 in exit () from /lib64/libc.so.6 #3 0x00000000004043d8 in handle_internal_command (argc=3, argv=0x7fffea4449f0) at git.c:379 #4 0x0000000000404547 in main (argc=3, argv=0x7fffea4449f0) at git.c:443 #5 0x000000349fd1c784 in __libc_start_main () from /lib64/libc.so.6 #6 0x0000000000403ef9 in ?? () #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.
