ID: 12227 Updated by: yohgaki Reported By: brueckner@respublica.de Old Status: Open Status: Feedback Bug Type: Output Control Operating System: Linux 2.2.16-SMP PHP Version: 4.0.6 New Comment: I guess you have ob_end_clean() or ob_end_flush() in your auto prepend file. Do you? Anyway, does this happen with 4.1.0? Previous Comments: ------------------------------------------------------------------------ [2001-07-18 06:13:58] brueckner@respublica.de One more comment which I forgot before: This does NOT happen when I do not use auto_prepend_file and call my function inside the main script instead. ------------------------------------------------------------------------ [2001-07-18 06:07:05] brueckner@respublica.de When using ob_start() with a script included via auto_prepend_file and then doing something like this: ob_start("my_flush"); function my_flush($buffer) { $buffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e", "parse(\"\\1\")", $buffer); return $buffer; } PHP 4.0.6 SIGSEGV's with this message in the error_log: [Wed Jul 18 11:55:08 2001] Script: '/home/htdocs/test.php' --------------------------------------- output.c(235) : Block 0x0824C940 status: Beginning: Overrun (magic=0x08294990, expected=0x7312F8DC) End: Unknown --------------------------------------- ./zend_execute.c(334) : Freeing 0x082A8CB4 (28131 bytes), script=/home/htdocs/test.php zend_variables.c(117) : Actual location (location was relayed) [Wed Jul 18 11:55:08 2001] [notice] child pid 30192 exit signal Segmentation fault (11) If I replace the line $buffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e", "parse(\"\\1\")", $buffer); with $newbuffer = preg_replace("/(<!--REPLACE\\s.*?-->)/e", "parse(\"\\1\")", $buffer); it works fine. Any ideas for a fix? Harry ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12227&edit=1
