@devnexen , @JohnTitor , CI is failing in main, and I have some observations.

I made PR #3693 . All checks have passed at some point in interval 11 May 00:28 - 01:29 UTC, so I assume main ( 8b9d1fe ) was okay at that time.

But then at 11 May 18:56 UTC I noticed that very same commit in main ( 8b9d1fe ) has failing CI with platform sparc64-unknown-linux-gnu.

So it seems some external resource was updated, and it broke CI

the sparc container tends to fail from time to time (e.g. timeout)

@devnexen , sparc64 is broken for two days. As you can see, in all PRs for last two days sparc64 did not success.

Also, CI result in this very PR ( #3698 ), says qemu-system-sparc64: terminating on signal 15 from pid 1165 (timeout), but also says /prog: /lib/sparc64-linux-gnu/libm.so.6: version GLIBC_2.38 not found (required by /prog)
