Package: man2html Version: 1.6g-16 Severity: normal Tags: upstream X-Debbugs-Cc: Alejandro Colomar <alx@kernel.org>, Paul Eggert <eggert@cs.ucla.edu>, "G. Branden Robinson" <branden@debian.org>, linux-man@vger.kernel.org, groff@gnu.org, tz@iana.org Dear Maintainer, The page tzfile(5) from tzdb-2024a manages to consistently produce a Segmentation fault with man2html(1).

These files use the format described in Internet RFC 8536. Each file is a sequence of 8-bit bytes. In a file, a binary integer is represented by a sequence of one or more bytes in network order (bigendian, or high-order byte first), with all bits significant, a signed binary integer is represented using two's complement, and a boolean is represented by a one-byte binary integer that is either 0 (false) or 1 (true). The format begins with a 44-byte header containing the following fields: Segmentation fault alx@debian:~/tmp$ dpkg -l | grep man2html ii man2html 1.6g-16 amd64 browse man pages in your web browser ii man2html-base 1.6g-16 amd64 convert man pages into HTML format I've refreshed this page today, and the previous version I used didn't have this crash. Below is the part of the diff that I think is responsible for the crash: diff --git a/man5/tzfile.5 b/man5/tzfile.5 index 45afecc10..867348d67 100644 --- a/man5/tzfile.5 +++ b/man5/tzfile.5 @@ -26,23 +26,24 @@ .SH DESCRIPTION and a boolean is represented by a one-byte binary integer that is either 0 (false) or 1 (true).

BTW, I noticed that the upstream homepage is dead: <http://users.actrix.gen.nz/michael/vhman2html.html>. Is this project defunct? Have a lovely day!
