For reasons I have not yet come to understand, qpdf 4.2.0 turns out not
to be binary compatible with 4.1.0. I am therefore recalling it.
Packagers should not package that version for a distribution. In the
very near future, I will release 5.0.0 with the same functionality but
with an acknowledgment that there is a binary interface change. In the
mean time, I also need to figure out what happened and put in place
measures to prevent a repeat.
