Here is the backtrace.

#0  0x0000000000402d29 in sha_eq (a=0xfefefefefefefeff <Address 0xfefefefefefefeff out of bounds>,
    b=0x563cdc "�6Cq�\234�w:0T��\177�\023p\214Q,") at cache.h:259
#1  0x000000000040456e in merge (h1=0x553ca0, h2=0x553d20, branch1=0x7fff92e5c27b "HEAD",

#2  0x0000000000405d89 in main (argc=-1830435858, argv=0x8) at merge-recursive.c:1362

I actually got this backtrace with the following script in git-merge-gdb

#!/bin/zsh

exec gdb -x =(print run $@) =git-merge-recursive
