--- Comment #9 from Shubham Narlawar <gsocshubham at gmail dot com> ---

I found the ICE - "internal compiler error: in hoist_memory_references, at
tree-ssa-loop-im.c:2615" with below testcase when compiled with -Og on trunk.
The testcase is obtained by fuzzing function attributes in Csmith - 


--------------------------Testcase---------------------------------------

a, b, c, d, f;
**e;
g() __attribute__((optimize("Ofast")));
g(h) {
  int *i = &a;
  for (; f;) {
    c = 5;
    for (; c; c--) {
      char *j = &b;
      **e = (h && d) == a;
      *i = 0;
      *j = 0;
    }
  }
}

-------------------------------------------------------------------------


I see above ICE has been fixed now.
