(edited both error messages for length; for the full messages, see the build log above)

A bus error usually signals unaligned access, which is probably a result from pointer magic that isn't strictly according to spec.

Note: SPARC isn't a release candidate architecture in Debian, so the continued support of ola in Debian stretch does not depend on this. However, it might be a good idea to look into this anyway.

I think I found the answer to my question, but as a first thing I'd probably like to add some more debugging to try and find out exactly where it's failing. If I do a branch on GitHub with some changes, can you get that built on SPARC? If so, roughly what sort of round trip times are we talking about?

Incidentally I see hurd-i386 is failing for a reason which may be something we can fix too, or is that not worth worrying about? Or alternatively we could drop that bit of functionality on hurd (which is only used in one RDM PID), so potentially the rest of OLA would work still.

I could do that, but if you think we'd have to do a lot of round trips it might be easier if we go down this route:

https://dsa.debian.org/doc/guest-account/

That's going to involve a bit more administrative work, but once done you can always reactivate your account for future issues, too.

Re: hurd: if you think it's worth it, then it's worth it. I'll just say that hurd sometimes lacks certain functionality, and that therefore it might be more trouble than it's worth.

I'm also seeing some sort of similar libs/acn/TransportTester failures on Windows, so hopefully they'll be the same cause...

Both tests are still failing on sparc64 for the current version of ola, see: https://buildd.debian.org/status/fetch.php?pkg=ola&arch=sparc64&ver=0.10.9.nojsmin-7.1&stamp=1757499977&raw=0

Access to SPARC machines for testing can be obtained through the GCC Compile Farm: https://gcc.gnu.org/wiki/CompileFarm

I can also test any test branches on my Debian sparc64 machine.
