* [3.12] gh-116767: fix crash on 'async with' with many context managers ↵Irit Katriel2024-05-011-2/+16
| | | | | | | | | | | | (GH-118348) (#118477) gh-116767: fix crash on 'async with' with many context managers (GH-118348) Account for `add_stopiteration_handler` pushing a block for `async with`. To allow generator functions that previously almost hit the `CO_MAXBLOCKS` limit by nesting non-async blocks, the limit is increased by 1. This increase allows one more block in non-generator functions. (cherry picked from commit c1bf4874c1e9db2beda1d62c8c241229783c789b)
