@hoodmane you can always do manual backports using https://pypi.org/project/cherry_picker/ :)

P.S. looks like you need to run make regen-cases to fix the CI.

The backport can be done manually, just start the PR subject with [3.11] (the rest should be the same).

And yes, please re-run regen-cases and commit Python/generated_cases.c.h.

Okay updated generated_cases as requested. Thanks.

GH-99514 is a backport of this pull request to the 3.11 branch.

Thanks!

@hoodmane Do you understand the buildbot failure? It seems related to this PR.

It looks unrelated to me? It's hard for me to tell but it doesn't look like the -DPY_CALL_TRAMPOLINE compile flag was passed so the trampolines shouldn't be active and hence this change should look like a no-op to that build:

checking LDSHARED... $(CC) -shared
checking BLDSHARED flags... $(CC) -shared
checking CCSHARED... -fPIC
checking LINKFORSHARED... -Xlinker -export-dynamic
checking CFLAGSFORSHARED... 

I think if the trampolines were enabled we would see -DPY_CALL_TRAMPOLINE in one of these places. Is there a place I can see exactly the build bot did?

I've created #99519 to fix it.

Thanks @sobolevn! (I'm glad I didn't have to figure out what was going on...)
