--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> ---
I can reproduce with 4.8 and trunk. Crashes due to division by zero in
fold_array_ctor_reference:
/* And offset within the access. */
inner_offset = offset % (elt_size.to_uhwi () * BITS_PER_UNIT);
Program received signal SIGFPE, Arithmetic exception.
0x00000000005e2448 in fold_array_ctor_reference (ctor=0x7ffff7627ca8,
ctor=0x7ffff7627ca8, from_decl=0x7ffff7535be0, size=0, offset=0,
type=0x7ffff7645540)
at /mnt/scratch/gcc-4.9-20130901/gcc/gimple-fold.c:2816
2816 inner_offset = offset % (elt_size.to_uhwi () * BITS_PER_UNIT);
(gdb) print elt_size
$1 = {low = 0, high = 0}
(gdb) q
Note that the test case has a static array of an empty struct type.

I'd say it's a dup.
