Diff of new easyconfig(s) against existing ones is too long for a GitHub comment. Use --review-pr (and --review-pr-filter / --review-pr-max) locally.

Are you using the latest easyblock? It is missing this commit from easybuilders/easybuild-easyblocks#3803

2025b is using GCC 14 that has new warnings. See pytorch/pytorch#166873

Patch added. Seems to only affect ARM

Oh, it is a C file. Updated the patch to also add it to C-flags

Looks like I need to set those values earlier. Can you try again?

Actual failure was an internal GCC compiler error:

Failure may be caused by this: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121027

There was a PR which should have worked around this, but seemingly the fix doesn't work?

Maybe we need to patch GCCcore/14.3.0 with this change?

That is not included in this (or any) release yet. I'll add it to the patch list

Would be an option, not sure if it is worth it: This EC is included since EB 5.1.0, although we did that in the past
