================
Comment at: clang/lib/Sema/SemaCoroutine.cpp:621
+        // returns a handle. In that case, even __builtin_coro_resume is not
+        // declared as noexcept, we claim that logically it does not throw.
+        if (FD->getBuiltinID() == Builtin::BI__builtin_coro_resume)
----------------
... it does not throw _into_ the coroutine that just suspended, but rather throws back out from whoever called coroutine_handle::resume().
