--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, so confirmed with -fno-checking.  With -fchecking I see

t.i:553:1: error: location references block not in block tree
  553 | } // namespace std
      | ^
_Coro_frameptr = 0B;
t.i:553:1: error: location references block not in block tree
_Coro_promise_live = 0;
t.i:553:1: error: location references block not in block tree
_Coro_gro_live = 0;
t.i:553:1: error: location references block not in block tree
_1 = 48;
t.i:553:1: error: location references block not in block tree
D.6221 = operator new (_1);
t.i:553:1: error: location references block not in block tree
...

so I wonder if that's an artifact of the reduction to invalid?  Can you
repeat the reduction in a way so the testcase keeps valid (accepted by clang)?
