Summary 0001561: Problem with back references to subpatterns in preg_match_all
Description When using a back reference within the pattern, the behaviour of preg_match_all differs from the original php implementation. The PEAR template engine (class HTML_Template_IT) doesn't work due to this bug. See attached file for a demonstration. The pattern used in the script is the same as used in the PEAR class.

The demo script contains the same pattern twice, firstly as a single-quoted, secondly as a double-quoted string. The original php implementation treats those differently, Quercus does not. Quercus always behaves as if it were double-quoted.
Steps To Reproduce
Additional Information The original php interpreter outputs:

array(1) {
  array(3) {
    string(60) "<!-- BEGIN testblock --> inside block <!-- END testblock -->"
    string(9) "testblock"
    string(14) " inside block "

Quercus outputs:
array(0) {

I'm sorry, the file upload didn't work but the rest of the bug was saved. See 1562 for a version including the demo script.
