--- Comment #2 from Noam Lewis <noamlewis at google dot com> ---
Not sure if same bug or different, we encountered this:

gcc (Debian 13.2.0-4) 13.2.0

$ cat /tmp/example.c 
typedef struct {
} a;
struct b {
  short c
};
struct d e;
struct d {
  struct {
    struct b f
  }
} inline g(struct b h) {
  i();
  fn3();
  e.f = h;
  return e;
}
typedef struct {
  int n;
  int j;
  struct b k;
  a l
} m;
static o(m h) {
  p(h.n, h.l, 1);
  g(h.k);
}
q() {
  struct b r = {};
  o((m){.2, .1, r, {}});
}

$ gcc-13 /tmp/example.c -O2 -c  -w -freport-bug
during IPA pass: inline
/tmp/example.c: In function ‘q’:
/tmp/example.c:29:3: internal compiler error: in modify_call, at
