Hello,
mame package uses mame -validate as %check step. It has recently
started
to cause problems on rawhide/aarch64:
- I had to cancel 0.258 build after 16 hours [1]
- 0.259 build is stuck since ca. 1600 UTC yesterday [2]
Other branches built fine for aarch64, and so did other arches for
rawhide. Additionally, there are no rawhide koschei builds since August
making it harder to find the potential culprit.
How can I investigate further? I might need to disable %check if the
reason cannot be found.
Best regards,
Julian

The build is still stuck. Do we have aarch64 machines accessible to
maintainers which could be used to see what the problem is? The last
we do have, please see

Thanks! Unfortunately it appears that aarch64 is only available as f38
and f37 which both finish the validation successfully. Rawhide is only
available as x86_64 which does not exhibit the issue either.
I will see if doing a rawhide mock build on f38 host is sufficient. This
is what koji seems to be doing anyway.
Best regards,
Julian
I managed to reproduce this on the aarch64 machine in mock. Validation
seems to get stuck right away at:
(gdb) bt
#0 0x0000aaaab5bddb08 in ___ZN4bgfx12VertexLayoutC1Ev_bti_veneer ()
hmm, couldn't it be related to the PAC & BTI feature [1]? I believe
someone mentioned some issues with it, probably here on the devel
list and the workaround was to disable the related compiler flags ...
The feature dates back to F33 whereas the breakage started after F39 was
branched. I discussed this with upstream [1] and the suspicion is that
the linker is misbehaving. I am attempting a build using lld to confirm.
Best regards,
Julian

#2 0x0000aaaaaef01570 in _start ()
One question: the binary in /builddir/build/BUILD still has symbols in,
correct?
yes, the files under /builddir/build/BUILDROOT/... are split into
stripped binaries and debuginfos
