Hasn't this been fixed now?

AFAIK it's still an issue. Albeit a very hard one to trigger. Also not
clear how to fix it short of hacking Stella internals.

The line is Int8 when = ourPlayerPositionResetWhenTable[myNUSIZ1 & 7][myPOSP1][newx];
A segfault can come from one of the array indices being outside the "legal" range.
To debug, you can find out the size of the array and include checks before the above line.
It is technically "hacking Stella internals" and obviously a Stella bug, not an ALE one. It may be fixed in the upstream Stella, but I'm not sure if there's even a mechanism or desire to keep in sync.

I just had the exact same crash in one of my trainings.
I have neither the action-sequence logged, nor file:lineno
-level stack trace, but the function-level stack trace looks exactly the same as reported here.
I believe it's unlikely my action-sequence was the same as reported here.
