Core files were getting stripped in some cases making them unusable:

How large are they? Do we have enough free disk space left on the runners?

How large are they? Do we have enough free disk space left on the runners?

The stripped core files I downloaded from the CI job were only 1.2MB, and when I tried to reproduce the issue locally I could make the test crash, but it only produced a 77MB core dump. I'm not sure why it was stripped as it should not exceed the current limit, but we recently added the step of removing the unneeded resources of the workers which frees up a few gigs that should be enough even if the crash dump is larger.
