From some microbenchmarks, this adds like 80ms or so on my machine, which seems negligible. |

GH-142416 is a backport of this pull request to the 3.14 branch. |

@zanieb: Merged, thanks. I backported the change to 3.14 since you wrote that 3.14.1 is also affected by the issue. I don't think that 3.13 needs a backported. Correct me if I'm wrong. |

test_jsoncasetest_highly_nested_objects_decodingfails under PGO on Clang 20 #140125It appears increasing this recursion depth of the object resolves the issue where it can fail to hit the stack limit on macOS during PGO.
The PGO test runtime seemed unaffected on macOS and the test runtime in CI here seems within noise.
