My build succeeded everywhere. Nevertheless, there were
some reports about issues with fibers (e.g.
https://bugs.ruby-lang.org/issues/20085). So we should
probably observe and if needed, apply some patch.
I did a build from my EL9 specific specfile here:
https://copr.fedorainfracloud.org/coprs/jackorp/ruby-builds/build/6848355/
It failed with a bunch of segfaults as well, it seems the
issue is reproducible on copr infra. The number of failed
tests is the same as with Pavel's build (103/1871)
Actually, the hw_info differs for copr and koji. Koji is
missing `paca pacg` (I guess those are related to the
mentioned `ASFLAGS=-mbranch-protection=pac-ret`), though
ssbs is present on both.
My copr build hw_info.log.gz:
https://download.copr.fedorainfracloud.org/results/jackorp/ruby-builds/fedora-rawhide-aarch64/06848355-ruby/hw_info.log.gz
Passed koji build hw_info.log.gz:
https://kojipkgs.fedoraproject.org//work/tasks/6817/111186817/hw_info.log
Also despite both of the infra are reporting the same
Vendor ID and Model Name, there are visually half the CPU
flags missing on Koji compared to copr.
Hoping that somebody is going to try the patch on my behalf
(unless I hit the issue myself ;) )
My second build hit 101 issues, similarly to the previous one.
Hm, I have just done the official build in Koji and again without
issues and I have never hit this even doing test in Copr, strange. I
am still on hold with the patch.
I am worried that Koji is doing something weird or has some weird
setup causing us not to trigger the bug.
I have an RPi 4 lying around, I'll try the build there, see if this
issue is affecting that platform, as Fedora supports those arm CPUs.
That was a fun excersize, but (un)fortunately RPi 4 arm CPU does not
seem to have PAC support, therefore I cannot reproduce the bug there.
I'd personally include the patch.
(I'd not like upgrading it to Fedora 40 in the future and finding out
Ruby programs are segfaulting around Fibers and whatnot.)
Alternatively, this might be worth bringing to fedora-devel, see if
someome there is wiser about that patch for ARM platforms.
