    Description

      I see a dramatic increase in the amount of memory required for construction of (arguably large) automata. It currently OOMs with 8GB of memory consumed for bit tables. I am pretty sure this didn't require so much memory before (the automaton is ~50MB after construction).

      Something bad happened in between. Thoughts, broustant, sokolov?
