--- Comment #6 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
An overnight csmith run came up with the same issue:

 ~ % cat crash1.i
int a;
int *b = &a, **c = &b;
int
main ()
{
  int **d = &b;
  *d = 0;
}

 ~ % gcc -O2 -flto crash2.i
lto1: internal compiler error: in ipa_single_use, at ipa.c:1299
