Now there’s a great question! I haven’t tested this on Lectrote at all; I figured if it worked in Frotz and Gargoyle, the Z-code was probably good.
But it seems Lectrote gives that error when the call stack overflows. So somewhere in the Z-machine runtime, the recursion is going one level deeper now, and that’s pushing it past a limit.
Does this happen with anything compiled with 1a/01-dev? Or is it specific to your game file?
