Subject Segfault with embedded URL's.
Date Mon, 13 Feb 2006 12:04:10 GMT

Hi all,

I'm getting a strange segfault when I try to expand a hash inside an <A>
tag, but only when I do it inside a table.


Here's my excact code;

[-
        $req = shift;
        $tfo = { %fdat };
        $tfo->{'reptype'} = 'GOO';
        @REPORTS = @ { $req->{REPORTS} };
-]
<a href="?[+ $tfo +]">TEST </a>
<table width=100% border=1>
 <tr>
  <td><a href="?[+ $tfo +]">[+ $REPORTS[$col]->{name} +]</a></td>
 </tr>
</table>

This fails promptly with a segmentation fault but no other error.

If however I remove ?[+ $tfo + ] from the second link and replace it
with static text, the page comes up fine and the first link "TEST"
contains the query string that I want to generate and the rest of the
table part is displayed so this error only seems to happen when I use
the same code for the "TEST" link and use it within a table loop.

My versions are; Apache/2.0.55 (Unix) Embperl/2.1.0 mod_perl/2.0.2
Perl/v5.8.6 


Can anyone shed any light on why this might be occuring?

Many Thanks
Craig
