The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202504/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:halide, so that this is still
visible in the BTS web page for this package.

Thanks.

Hi.
Looks like it is failing with SIGILL "illegal instruction",
what is the CPU there? /proc/cpuinfo?

Looking at the code:
https://github.com/halide/Halide/blob/v19.0.0/test/correctness/tiled_matmul.cpp#L254
I would guess that the CPUID claims to support new AMX instruction set,
but when actually executing such instructions, barfs.

and each time it was made "from scratch". This is not a hand-made
build with dpkg-buildpackage, this was a mass rebuild using sbuild.

In this case they are c7i and m7i machines from AWS, so they have
a 4th Generation Intel Xeon Scalable processor.

The cpuinfo is attached.

(If you need a VM to reproduce, please contact me privately)

Thanks.

Right, so that CPU does claim to have AMX support.
But is AMX supported in such a virtualized environment?
https://community.intel.com/t5/Intel-Tiber-Developer-Cloud/Can-t-run-AMX-Instructions-on-Intel-Xeon-4th-Gen-Scalable/m-p/1532428
suggests not. Could you please file an issue with AWS?
I really feel like the issue is on their end...
Thank you.

Maybe it is, but it is not easy for me to file an issue with them,
because I'm just using an account for which I have limited permissions

Given that it's a single test the one that fails, I was thinking about
disabling it with a changelog entry like this:

"Temporarily disable test foo, since it does not seem to work in
some hardware configurations."

Would you accept such a patch?

(I honestly think it would be a lot better than nothing).

Thanks.

This feels like disabling tests because they happen to fail because of bad ram.
Because that is exactly what is going on - the system is knowingly
lying about the CPU features it provides.
I am not enthusiastic about breaking the package's test suite any further.

forwarded 1103553 https://github.com/halide/Halide/issues/9191
thanks

Hello. I've forwarded this issue to the above address.

For the record, I don't think the comparison with bad RAM is fair.
A better example would be perhaps the way Linux does not blindly
believe the information provided by the system BIOS, which can
also be a "lie" which is not to be trusted.

In either case, I understand that you don't want to disable the
test. Hopefully (if you read the above link) the authors might fix it
in a way which makes everybody happy, as apparently they already did
something similar in the past.

Thanks.

Thank you!

Hi.

The authors have provided a patch and have asked me to test it, but I can't,
because it does not apply cleanly on top of the current Debian package
halide 21.0.0-4.

This is why I added a mention to your github user in the issue, in
case you have some idea (hope you don't mind).

(For example, if you manage to apply the patch cleanly and put it in
some salsa branch, i.e. some sort of pre-release, I could test from there).

Thanks.
