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. ^ permalink raw reply [flat|nested] 2+ messages in thread
