Package: htmldoc
Version: 1.8.24-2
Severity: important
Tags: patch
I tried to compile the documentation of privoxy using htmldoc and had
to notice, that it runs into segmentation faults. I reduced the html
file to a minimal one:
$ htmldoc -t pdf -f test.pdf test.html
PAGES: 3
Segmentation fault
$ cat test.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title>baz</title>
</head>
<body>
<h1>bar</h1>
<ul>
<li>foo</li>
</ul>
</body>
</html>
When this happens I see the following message in the kernel log
(dmesg):
htmldoc[31826]: segfault at 000000fa00623260 rip 00002aaaabf59961 rsp
00007fffff84efd0 error 4
htmldoc[32421]: segfault at 000000fa00622370 rip 00002aaaabf59961 rsp
00007fffffdfbd80 error 4
htmldoc[32425]: segfault at 000000fa00622370 rip 00002aaaabf59961 rsp
00007ffffff66440 error 4
(one line per htmldoc run).
The problem does not exist on a i386 sid system, but as you can see,
it happens on nearly every html file on amd64.
I just got the new upstream version 1.8.25 (compiles out of the box
with the debian 1.8.24-2 diff) and with this version all problems seem
to have gone away.
In the strace output I see, that the problem occurs while/after
reading Symbol.afm and in the changelog of 1.8.25 I found the
following entry:
- HTMLDOC could crash when loading the Symbol.afm file
(STR #93)
So I had a look at this bug report (http://www.htmldoc.org/str.php?L93)
and found a point to SVN version 1428, which solves this problem.
I extracted the patch from SVN 1428 and this one-line patch solves the
problem for me.
This is quite important to me, because htmldoc is a build dependency
of privoxy and if htmldoc runs into segmentation faults when compiling
the privoxy documentation, the privoxy packages are broken (at least
on amd64, but I fear that the same happens on other 64 bit
architectures as well).
If you aren't able to create a new package soon, please tell me, so I
can upload an NMU.
