OK, This is a strange one..... the whole application works perfectly on 4.0*/4.1*, but we started testing with 4.2.1
 
I'm filing it as a trans-sid bug (as thats whats noticable the most)- but it could be 
 - output buffer?!?
 - class variable issues..
 - other weird stuff....
 


------------Part of the html/php page  
<table border="0" cellpadding="3" cellspacing="1" width="62%">
<tbody>
<tr class="cleartable">
<td width="10%"><? if ( $auth->is_Requestor() ) { ?><img src="<?=htmlspecialchars($config->simple_base_url) ?>/translatorsdb/newpo
sts.gif" width="15" height="14" border="0" alt=""> </td>



-----------Output from the html page

<table border="0" cellpadding="3" cellspacing="1" width="62%">
<tbody>
<tr class="cleartable">
<td<img src="/translators/translatorsdb/newposts.gif" width="15" height="14" border="0" alt=""> </td>

___^___ notice the misformed html in the output.


the output is somehow getting messed up...

CONFIGURE LINE
 './configure' '--with-apxs=/usr/local/sbin/apxs' '--with-config-file-path=/usr/local/etc' '--enable-versioning' '--with-system-regex' '--disable-debug' '--enable-track-vars' '--without-gd' '--with-mysql' '--enable-trans-sid'
 
 
QUICK OVERVIEW OF FEATURE USED:
trans-sess-id sessions are being used  and it does manage to replace all href with the 'sid' before (roughly) the 4138th character, 
after that, even if the break is in a valid place 'htmlwize', it will not replace any hrefs after that postition.

the file/code above is included from within a class instance method 
eg. something like this.
class default_page {
	var $template = "home.html";
	function output() {
		$template->compile($this->template);
		
		global $session,$config;
		$auth = &$session->auth;
		include($template->ouput_file);
		
	}
}
