[Bug middle-end/41256] New: ICE with -ftree-parallelize-loops=2 in locator_location at cfglayout.c:517

[ubizjak at gmail dot com]

Following testcase fails when dumping RTL debug files (-da):

--cut here--
int e[1024];

int
foo (void)
{
  int i;
  for (i = 0; i < 1024; i++)
    e[i] = i;
  return 0;
}
--cut here--

gcc -O2 -ftree-parallelize-loops=2 -da r.c
<built-in>: In function âfoo._loopfn.0â:
<built-in>:0:0: internal compiler error: vector VEC(int,base) index domain
error, in locator_location at cfglayout.c:517
Please submit a full bug report, <etc>.

Somehow annoying bug, since it breaks debugging.
