I submitted this as a bug for 5.1.6 so if there is another revision on the 5.1 line the fix would be in it. The moment 5.2.0 is officially released this issue is void. ------------------------------------------------------------------------ [2006-09-22 21:09:25] iliaa@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip Seems to work in latest CVS, no memory errors are being reported by valgrind either. ------------------------------------------------------------------------ [2006-09-22 14:11:25] starson dot hochschild at mtginfo dot com Description: ------------ I know: php5.1.0 has this problem php5.1.6 has this problem php5.0.5 does not have this problem php5.2-win32-200609211830 does not have this problem php6.0-win32-200609211630 does not have this problem I assume: php >= 5.1.0 <= 5.1.6 has this problem php4.x does not have this problem php >= 5.0.0 < 5.1.0 does not have this problem I have tested this on both Win32 and Linux.
