Again, you should not be forcing closeOpaque to be non-NULL.  It's
opaque, after all.

Passing 'false' to %d looks odd, but works.  If, per my 2/5 comments,
you merge wantClose into closeReason, then you'd have an int instead of
a bool to print here.

ACK, once you fix the non-NULL opaque limitation.
