…o.graph _build_graph_for_future appended FrameCallGraphEntry(coro.cr_frame) in the ag_await branch; async generators expose ag_frame. The line is unreachable via standard async-for (async_generator_asend has neither cr_await nor ag_await) but is reachable from duck-typed chains.

Fair point on the sentinels. Worth flagging: the Duck-typed stubs are the only way to drive that branch. Open to closing this if dead-code cleanup isn't worth the churn. |

Fixes gh-148736.
One-line correction: the
ag_awaitbranch of_build_graph_for_futurewas usingcr_frameinstead ofag_frame. Added a regression test that constructs a minimalag_awaitchain and exercises the walker directly.
