RISC-V runner segfault with cache

[tgross35]

The run at https://github.com/rust-lang/compiler-builtins/actions/runs/23674147811/job/68973834693?pr=1138 failed with the following:

I don't think it's happened consistently but fyi in case you have any ideas @yuzibo.

Yeah, this is very odd.

I do not think this is one real bug for caching compiler-rt on the runner, as we have many jobs already, including in my repo forked, this is the first time to see it. But I do not have evidence either.

Or was another memory-intensive job running at the same time? I suspect this. BTW, I will do my best to avoid running other jobs on the host.

I'll just close this since I don't think there is something actionable. Just something to keep an eye on if it happens again.

I don't think there is any problem running other jobs. Shouldn't segfault either way of course :)
