ber_pvt_snprintf() core dumps on Solaris 2.5.1/SPARC and Tru64 UNIX 4.0D. The
implementation via pipe() seems way ugly. I gutted it in favor of trio:
  http://ctrio.sourceforge.net

Patch in ftp://ftp.openldap.org/incoming/chinayoung-021126.2.

BTW, lftp, curl, and other projects use trio. Maybe trio is overkill for what
you need (ncurses has a private implementation that is smaller) but it is easy
to integrate and it supports the various printf arguments.
