@cherrymui points out that there are existing s390x timeout issues related to TestStackGrowth.

bcmills commented May 3, 2023

The failure in #57379 (comment) doesn't look particularly specific to TestCgoCallbackGC or TestStackGrowth — nothing seems to be wedged, it looks like the builder just took a little too long to run the runtime tests overall.

(That failure probably belongs in #58901, but went to this issue because both match and this one is older.)

(I suggest that this issue be closed and removed from the Test Flakes project so that new failures will go to the other open issues.)

Agreed. Done.
