On a RH6 system, % /usr/bin/man2html /usr/man/man5/terminfo.5 takes infinite time and infinite memory (or at least 128MB). It displays a part of the document, then goes metaphysical. All other manpages on the system are rendered correctly. PolyglotMan (rman) handles that manpage correctly.
I have verified this to be true on a test machine in the test lab with a stock 6.0 install.
applied patch from Andries.Brouwer and made new package for rawhide.
