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)?
