["ubizjak at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

Minimized testcase (from other bootstrap failure):

--cut here--
typedef struct
{
  struct
  {
    int how;
  } reg[64 + 1];
}
_Unwind_FrameState;

alpha_fallback_frame_state (_Unwind_FrameState * fs)
{
  long i;

  for (i = 0; i < 31; ++i)
    fs->reg[i + 32].how = 0;
}
--cut here--

~/gcc-build-test/gcc/cc1 -O2 -quiet t1.c
t1.c: In function ?alpha_fallback_frame_state?:
t1.c:10:1: error: definition in block 3 does not dominate use in block 2
for SSA_NAME: i_11 in statement:
D.2028_3 = i_11 + 32;
t1.c:10:1: internal compiler error: verify_ssa failed
