to accessible_mask. Add Copy version and use it in mask_keep_states().

double-free errors.

Demaille for its help.  This should fix a bug observed by Joachim Klein

This bug caused tgbatest/ltl2dstar.test to fail but because I had
no ltl2dstar on my computer for a while, I only discovered it after
David Müller and Joachim Klein reported a bug against ltlcross.
It might be the case that their bug is different (I can't reproduce it
using their format), but I hope it was caused by this as well.
