I'm seeing a memory overrun under PHP 4.3.0pre2 (debug) running under Windows 2000 ISAPI. Using these two scripts: test.php -------- <html> <head> <link rel="stylesheet" href="stylesheet.php" type="text/css"> </head> <body> <span class="text">styled!</span> </body> </html> stylesheet.php -------------- <?php // only reload this version of the stylesheet ever hour header("Cache-Control: max-age=3600"); ?> .text { font-size: 12px; color: red; font-family: Arial, Helvetica, Verdana, sans-serif } If in a browser window I refresh this page repeatedly within about ten seconds I get an access violation and this debug output: --------------------------------------- C:\Work\php-source\php-4.3.0pre2\ext\bcmath\libbcmath\src\init.c(72) : Freeing 0x01B85050 (1 bytes), script=c:\inetpub\wwwroot\test.php Last leak repeated 2 times C:\Work\php-source\php-4.3.0pre2\ext\bcmath\libbcmath\src\init.c(57) : Freeing 0x01B84FF8 (29 bytes), script=c:\inetpub\wwwroot\test.php Last leak repeated 2 times --------------------------------------- c:\work\php-source\php-4.3.0pre2\zend\zend_ptr_stack.c(77) : Block 0x01B80650 status: Beginning: Overrun (magic=0x01B80178, expected=0x7312F8DC) End: Unknown --------------------------------------- c:\work\php-source\php-4.3.0pre2\zend\zend_hash.c(534) : ht=0x018f3484 is already destroyed c:\work\php-source\php-4.3.0pre2\zend\zend_hash.c(660) : ht=0x018f3548 is already destroyed --------------------------------------- c:\work\php-source\php-4.3.0pre2\zend\zend_ptr_stack.c(77) : Block 0x01B00650 status: Beginning: Overrun (magic=0x01B00178, expected=0x7312F8DC) End: Unknown --------------------------------------- c:\work\php-source\php-4.3.0pre2\zend\zend_hash.c(534) : ht=0x01894df4 is already destroyed c:\work\php-source\php-4.3.0pre2\zend\zend_hash.c(660) : ht=0x01894eb8 is already destroyed --------------------------------------- Any tips on how to track down what's going on here?
