--- Comment #6 from John David Anglin <danglin at gcc dot gnu.org> ---
gdb temacs:

(gdb) p (int)MALLOC_ALIGNMENT
$2 = 8
(gdb) p (int)LISP_ALIGNMENT
$3 = 16
(gdb) p (int)MALLOC_IS_LISP_ALIGNED
$4 = 0

See src/alloc.c in emacs source.

I think LISP_ALIGNMENT is 16 because of the pthread lock alignment issue.
Since MALLOC_IS_LISP_ALIGNED is 0, we run out of memory.

Either we change the malloc alignment to 16 and put MALLOC_ABI_ALIGNMENT
back to 128, or I reinstall the lock alignment patch.  We might still run
out of memory with a malloc alignment of 16.  It not good to lie
about the malloc ABI alignment.  The lock alignment patch breaks ABI
and who know what.  It's probably best fix...
