 Status:           Analyzed
 Bug Type:         Zend Engine 2 problem
 Operating System: windows2000sp4
 PHP Version:      5CVS-2003-07-16 (dev)

 New Comment:

If you do it like this it works:

class TextSanitizer
{
 function &htmlSpecialChars($text) {
  $foo = preg_replace("/&/i", '&', htmlspecialchars($text,
ENT_QUOTES));
  return $foo;
 }
}

So would it really be *that* hard to make it work?

It never really worked (caused memory corruption).
Unlikely to be changed, since it doesn't make sense, but we'll see.

Actually this is not a bug, but just another BC break, but a pretty
huge one. I think it's too much of a problem not to address it.
