Among random "better safe than sorry" changes, the real fix is in changing "4" for "5" above _find declaration. This off-by-one error had that word, which is the root word in z80, have a 0x01 prev field instead of a 0x00 one. When all memory was initialized to zero, it didn't matter, we ended up hitting 0 prev and considered ourselves properly at the end of dict. When memory wasn't initialized, however, we would end up jumping at all kinds of places, leading to random behavior.
