(apparently) leaky zend

Hi All, I've been noticing a whole bunch of memory leaks that appear to be coming from zend while running a complex script. zend_hash.c(202) : Freeing 0x088D11E4 (20 bytes), script=/wwwroot/view.php Last leak repeated 37 times ./zend_execute.c(2144) : Freeing 0x089D8E3C (48 bytes), script=/wwwroot/view.php zend_variables.c(131) : Actual location (location was relayed) Last leak repeated 27 times zend_hash.c(291) : Freeing 0x08A86FD4 (46 bytes), script=/wwwroot/view.php Last leak repeated 191 times zend_hash.c(461) : Freeing 0x08A943E4 (76 bytes), script=/wwwroot/view.php Last leak repeated 18 times plus a load more like it. Before I file a bug report, I wanted to see if I could track it down, but it's proving difficult. The script makes heavy use of PCRE and use of the jstring extension, so my money is on one of those two, but I can't see anything obvious that might be causing it. What concerns me is that it appears that the same pointers are being freed multiple times. Could someone enlighten me as to what these messages actually mean so that I can track it down? --Wez.
