Is this repeatable with Go 1.20.6?

I have not been able to make this re-occur on 1.20.6, 1.20.7, nor 1.21.0

Thanks. Unfortunately, this isn't a lot to go off of. It's almost certainly some kind of memory corruption, since this crash indicates an inconsistency in the memory allocator fast path which hasn't changed recently and is executed quite often (so crashes due to bad logic like this tend to flush out very fast).
