The stack trace implies loading a nil heapArena struct. I'm not sure how this could happen (for instance due to a race). I'll look into it.

I want to look into whether this is actually only happening on Darwin.

prattmic · 2023-03-01T20:28:26Z

I see it once on freebsd in 2021:

@golang/runtime, is this another symptom of #60449 or do we think it has a separate root cause?

mknyszek · 2024-01-11T17:23:07Z

I believe it's another symptom. I recall investigating this and concluding that it's memory corruption. I double-checked just now and yeah, the failing line doesn't really make sense (that index is write-once, but if it was just allocated and the wrong index was being set up, then we'd be seeing these crashes in a lot more places).

mknyszek · 2024-01-11T17:23:44Z

I added this as a condition to #60449, closing now as a duplicate.
