Comment 18 for bug 968766

Building the following testcase with -O -ftree-vectorize on x86_64:

long
test (int *x)
{
  unsigned long sx, xprec;

  sx = *x >= 0 ? *x : -*x;

  xprec = sx * 64;

  if (sx < 16384)
    foo (sx);

  return xprec;
}

results in an ICE:

crash1.c:5:1: internal compiler error: vector VEC(vec_void_p,base) index domain error, in vinfo_for_stmt at tree-vectorizer.h:628

(When building with --disable-checking, we get a segmentation fault instead.)
