------- Comment #1 from pinskia at gcc dot gnu dot org  2006-04-01 00:52 -------
Confirmed, reduced testcase:
void
ruby_re_compile_fastmap (char *fastmap, int options)
{
  int j;
  for (j = 0; j < (1 << 8); j++)
   {
     if (j != '\n' || (options & 4))
        fastmap[j] = 1;
   }
}

-----
you can get the error with -O1 -funswitch-loops -ftree-vectorize
