ID: 62234 User updated by: manchokapitancho at gmail dot com Reported by: manchokapitancho at gmail dot com Summary: PHP crashes if a load of code is loaded. -Status: Open +Status: Closed Type: Bug Package: Scripting Engine problem Operating System: win 7 PHP Version: 5.4.3 Block user comment: N Private report: N New Comment: My bug seems to be a duplicate of this one. https://bugs.php.net/bug.php?id=61998 I had 3 occurrences of use X as Y. After removing them, there were no more crashes. I tried the latest snapshot and I have no more problems with the original code. Previous Comments: ------------------------------------------------------------------------ [2012-06-06 05:54:02] manchokapitancho at gmail dot com Reproduced in CLI mode. Ran the same code and simulated some $_SERVER values. I get 1:1 result so it is not Apache related. The message I get at the end of the script is: zend_mm_heap corrupted. ------------------------------------------------------------------------ [2012-06-05 16:00:33] manchokapitancho at gmail dot com Description: ------------ I am using Apache 2.2 + PHP 5.4. After several crash situations (from apache log "Parent: child process exited with status 1 -- Restarting."), I've managed to isolate a problem. Since I don't know what it is exactly, here I list the symptoms: 1. It's not related to a specific code fragment. I am able to reproduce the crash by adding different code in different files. 2. Too much code leads to a crash. If I have a working code and I add for example 30 more functions to a class, I get a crash. 3. Adding more data does not affect the situation. By data I mean actions like changing $a = [1,2,3] to $a=[1,2,3, ....1000]. 4. The entire script is executed till the end and then the crash happens. I asume this happen when the cleanup routines are executed. 5. The crashes are not memory related. I saw cases when the crash happens at around 612K and others when the script run ok at around 619K. 6. I've tested with xdebug on and off. No significant difference is present. If I don't have xdebug active, I need a few more empty functions into the code in order to reproduce the crash. Here I've put some interesting observations that I've had. http://crop-factor.net/php54crash.png phpinfo says: System Windows NT 6.1 build 7600 (Windows 7 Enterprise Edition) i586 Build Date May 8 2012 00:47:34 Compiler MSVC9 (Visual C++ 2008) Architecture x86 Configure Command cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=C:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=C:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8- 11g=C:\php-sdk\oracle\instantclient11\sdk,shared" "--enable-object-out- dir=../obj/" "--enable-com-dotnet" "--with-mcrypt=static" "--disable-static- analyze" "--with-pgo" Server API Apache 2.0 Handler PHP API 20100412 PHP Extension 20100525 Zend Extension 220100525 Zend Extension Build API220100525,TS,VC9 PHP Extension Build API20100525,TS,VC9 Debug Build no Thread Safety enabled ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62234&edit=1
