            Bug ID: 60193
           Summary: [4.7.4/4.8/4.9 regression] ICE on big nested frame
           Product: gcc
           Version: 4.7.4
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal

The fix for PR target/56807 has introduced ICEs on big nested frames:

eric@polaris:~/gnat/bugs/N213-061> cat t.c
void foo (int i)
{
  void nested (void)
  {
    char arr[1U << 31];
    arr[i] = 0;
  }

  nested ();
}
eric@polaris:~/gnat/bugs/N213-061> ~/gnat/gnat7_47/x86_64-pc-mingw32/gcc/cc1
-quiet t.c
t.c: In function 'nested':
t.c:7:3: internal compiler error: in change_address_1, at emit-rtl.c:2001
