From Atari Age and Phaeron:

I think I might have found the crash that fjc was running into... there was a problem in the debugger where the history pane code could overflow the stack. Basically, when I fixed the stack unwrapping code so that it could trace JSR/RTS around the $1FF-$100 boundary, it then caused a problem where crashed 6502 code could nest more deeply than the tree node allocation code could handle. Sigh. Fixed version:

I hadn´t intended to push it out yet, but this build also has more work on the LLE kernel, such as full support for PBI devices. It also contains a printer (P driver. I had figured that I didn´t need one because no one uses it and I didn´t emulate the printer device at an SIO anyway, but with my dumb luck I found a game that opens P: even though it doesn´t need it... grr.
