Thanks for the PR!

Oleg: I re-ran and ASAN succeeded, so it's probably a flaky test :(

Sorry,@OTheDev, I could not cleanly backport this to3.11 due to a conflict.
Please backport usingcherry_picker on command line.

Sorry@OTheDev, I had trouble checking out the3.10 backport branch.
Please retry by removing and re-adding the "needs backport to 3.10" label.
Alternatively, you can backport usingcherry_picker on the command line.

@erlend-aasland It looks likePy_EnterRecursiveCall() is not in_bisectmodule.c in 3.11 and 3.10, so I think a backport isn't needed?

Yeah, looks like Dennis added them recently. No backport, then! :)
