Sorry, something went wrong.
@prattmic notes that CPU profile is broken on openbsd-arm, so as long as we only see issues there, this is probably not worth tracking other than to skip these tests. Assigning to @prattmic who volunteered to do that.
Actually, this just tests the buffer itself, it doesn't do profiling. I'll take a closer look.
The failing case is this one https://cs.opensource.google/go/go/+/master:src/runtime/profbuf_test.go;l=144-146;drc=b788fd80e68addd181983ca589d28bc1075f4a36.
The timestamp (99/0x63) is correct, but the length (got 5 want 8) and header/stack data are incorrect. Nothing stands out here, I'd like to see more failures to see if this is a pattern.
