           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

While fixing bootstrap for MPX I faced this new ICE:

> cat gensupport.c
int *fn1() {
  int *r = fn1();
  if (r == __null)
    return r;
}

> g++ gensupport.c -O1 -mmpx -fcheck-pointer-bounds

And the guilty revision is:
