@mknyszek requested issue #72991 to be considered for backport to the next 1.24 minor release.

@gopherbot Please open a backport issue for Go 1.24.

This is a regression in 1.24 only. Unfortunately the fix uncovered some subtly wrong and scary things about asynchronous preemption. The changes include a fix, but given how subtle it is, we have decided to let it soak for a little bit before actually committing to the backport. Apologies to those waiting. There's a risk of introducing random crashes into programs not affected by this issue.
