Yes.  My Emacs did the same.

In gdb with "-nw" the stack trace is as follows:

#0  0x90004248 in szone_size ()
#1  0x000b0e30 in xrealloc (block=0x0, size=481) at alloc.c:542

#8  0x00003728 in start ()

Then trying to restart with a file name:

Program received signal EXC_BAD_ACCESS, Could not access memory.
0x90013b70 in large_entry_for_pointer_no_lock ()

I'll save this binary if you need me to do additional testing.
