Dear Uxners,

The stack printing routine seems to be broken when the stack pointer
wraps around back to -1 from starting position.

Minimal example:

|100 POP #010e DEO BRK

Current behavior: It seems to be printing the complete stack over and
over infinitely.

Expected behavior:  I would expect to either print the stack something like:
WST 00 00 00 00 00 00 00 00|<
RST 00 00 00 00 00 00 00 00|<

Taking into account that the stack "underflowed" either using a marker
or just not printing infinitely.

Or print the complete stack just once, since it is wrapped around and
it attempts to print the whole stack, I would understand that, but the
problem is that it repeats infinitely.

Best regards,
Ismael Venegas Castelló

Hi Snufkin 🙂

Thanks for spotting this one!
Pushed a fix to uxnemu and uxn11.
