[Bug optimization/13363] New: [tree-ssa] ICE with arrays

[pinskia at gcc dot gnu dot org]

Try to compile this at -O1 or above:
enum machine_mode { MAX_MACHINE_MODE };
enum insn_code { CODE_FOR_nothing };

enum insn_code fixtab[(int) MAX_MACHINE_MODE][(int) MAX_MACHINE_MODE][2];
enum insn_code fixtrunctab[(int) MAX_MACHINE_MODE][(int) MAX_MACHINE_MODE][2];

void
init_optabs ()
{
  int i, j;
  enum insn_code *p;


  for (p = fixtab[0][0];
       p < fixtab[0][0] + sizeof fixtab / sizeof (fixtab[0][0][0]);
       p++)
    *p = CODE_FOR_nothing;

  for (p = fixtrunctab[0][0];
       p < fixtrunctab[0][0] + sizeof fixtrunctab / sizeof (fixtrunctab[0][0][0]);
       p++)
    *p = CODE_FOR_nothing;
}


You get:
new.c: In function `init_optabs':

new.c:11: internal compiler error: in maybe_fold_offset_to_array_ref, at tree-ssa-ccp.c:1534

It passes with 2003-12-06 version of the tree-ssa so it is a recent regression.

Note that above CVS commits were added accidentially to this PR due to 
a typo in the PR number.
