I was hoping this problem would have been fixed in 2.72, but when I
send this email:
https://po2.uni-stuttgart.de/~ruslucas/email.txt
through spamassassin (with Razor2 2.72 on a Red Hat 9.0 system):
spamassassin -tD < email.txt
I still get a Segmentation fault.

When I patch 2.72 with:

--- deHTMLxs.xs.orig    2005-06-20 14:24:34.000000000 -0600
+++ deHTMLxs.xs 2005-06-20 11:39:32.000000000 -0600

+            *(raw + size -1) = '\0';
             if ( (cleaned = malloc(size+1)) && 
                  (res = html_strip(raw, cleaned))  // html_strip will memset cleaned to 0
                  ) {

The Segmentation fault no longer appears. I have no idea how this work-around
affects the program.

I created the patch by using this as a reference:
http://sourceforge.net/tracker/index.php?func=detail&aid=1003857&group_id=3978&atid=303978
which refers to an older version of deHTMLxs.xs.

It appears the only reason it did not die on FreeBSD is because the
package maintainer had applied these work-arounds, which have been
applied to some extent, but not fully, in version 2.72.
