Re: [Gcl-devel] Something wrong in the printer?

[Camm Maguire]

Greetings!  Your expression overflows the pretty print queue.  It will
work if the Q_SIZE in notcomp.h is enlarged (e.g. doubled).  Also in
stock GCL with

(setq *print-pretty* nil)

Perhaps someone could suggest a good Q_SIZE parameter now that we are
adjusting memory defaults, etc.?

Take care,
