"You have found a bug in DDD"

Not sure if this warrants an email. I'm using ddd on osx, installed with
homebrew, thus there is a lot of room for error on my end to have caused
whatever gave me the bug message. Just in case, I'm sending you the state
of my machine in case it helps you improve ddd.

I've attached my code in a tar.gz file. I attempted to run with this
terminal command:

clear && clear && make && ddd ./mazes-for-programmers.out

I've also attached the ~/.ddd/log
