@prattmic requested issue #62440 to be considered for backport to the next 1.21 minor release.

@gopherbot please backport to 1.21. This is a fatal crash with no workaround for applications using C coroutine libraries and calling into Go. The fix here is fairly complex, so this is a medium+ risk backport, but we don't have a simpler workaround to backport. That said, the fix has baked in post-submit for 2+ weeks without further issue.

What's the status on this one? We were waiting for any bugs to shake out on tip, I believe?
