#46950 [NEW]: PHP 5.2.8 IIS ISAPI Crashing - Was Fine in 5.2.6

From: w dot ashcroft at redfoxuk dot com Operating system: Windows 2003 PHP version: 5.2.8 PHP Bug Type: Unknown/Other Function Bug description: PHP 5.2.8 IIS ISAPI Crashing - Was Fine in 5.2.6 Description: ------------ Since upgrading to PHP 5.2.8, one of our servers has started to crash once or twice a day - I assumed PHP was the cause and DebugDiag points at PHP too. I am not sure how to reproduce the crash on demand. Zend Optimizer isn't enabled, it was the first thing I tried - still crashes without it. Reproduce code: --------------- n/a Expected result: ---------------- n/a Actual result: -------------- In w3wp.exe__PID__1652.dmp the assembly instruction at php5ts!zend_hash_del_key_or_index+10a in \\?\C:\PHP5\php\php5ts.dll from The PHP Group has caused an access violation exception (0xC0000005) when trying to write to memory location 0x00000000 on thread 0 Thread 0 - System ID 904 Entry point 0x134c7078 Create time 25/12/2008 14:58:47 Time spent in user mode 0 Days 00:00:28.703 Time spent in kernel mode 0 Days 00:00:24.328 This thread is blocked by an unhandled exception Function Arg 1 Arg 2 Arg 3 Source php5ts!zend_hash_del_key_or_index+10a 138f1e68 0308a8cc 00000012 php5ts!zend_unregister_functions+53 0308d070 ffffffff 00000000 php5ts!module_destructor+7d 01c10178 138fa768 022d2160 php5ts!zend_hash_apply_deleter+97 022d2160 01c10140 138fa768 php5ts!zend_hash_graceful_reverse_destroy+13 022d2160 1394aa08 138fa768 php5ts!zend_shutdown+2e 138fa768 138fa768 138fa768 php5ts!php_module_shutdown+35 138fa768 00000000 00000000 php5ts!php_module_shutdown_wrapper+f 022d2060 01df265d 01df0000 php5isapi!DllMain+70 01df0000 00000000 00000001 php5isapi!_DllMainCRTStartup+50 01df0000 00000000 00000001 ntdll!LdrpCallInitRoutine+14 01df260d 01df0000 00000000 ntdll!LdrShutdownProcess+182 00000000 00000001 138fb818 kernel32!_ExitProcess+43 00000001 77e8f3b0 ffffffff kernel32!ExitProcess+14 00000001 0552f174 77bcaefc msvcrt!__crtExitProcess+32 00000001 138fb91c 00000058 msvcrt!_cinit+d2 00000001 00000000 00000000 msvcrt!exit+11 00000001 01e0a00b 020c330c php5ts!zend_mm_panic+24 020c330c 020c306c 00000001 php5ts!_zend_mm_alloc_int+bb 00000181 0000004f 020c306c php5ts!_zend_mm_realloc_int+b6d 138fb818 00000000 0000004f php5ts!_erealloc+43 00000000 0000004f 00000000 php5ts!xbuf_format_converter+7c 0552f474 020c306c 0552fe10 php5ts!vspprintf+29 0552f4ac 00000400 020c306c php5ts!php_error_cb+3a 00000010 020c27dc 00000000 php_soap!soap_error_handler+9c 00000010 020c27dc 00000000 php5ts!zend_error+43e 00000010 020c306c 01e9846d php5ts!_zval_internal_dtor+33 13967e38 00000000 01e9c687 php5ts!_zval_internal_ptr_dtor+1d 13967e9c 13967ec8 13967ed4 php5ts!zend_hash_destroy+27 13967d10 13968068 01e9c687 php5ts!delete_internal_hashtable+d 13967ed4 00000015 1397e3e8 php5ts!zend_hash_destroy+27 137365a0 138fa768 01edf785 php5ts!php_win32_core_globals_dtor+3c 1397e3e8 138fa768 01df0000 php5ts!ts_free_thread+85 01df265d 01df0000 00000003 php5isapi!DllMain+17 01df0000 00000003 00000000 php5isapi!_DllMainCRTStartup+50 01df0000 00000003 00000000 ntdll!LdrpCallInitRoutine+14 01df260d 01df0000 00000003 ntdll!LdrShutdownThread+d2 134c7078 00000000 0552ff9c kernel32!ExitThread+2f 00000102 134c7078 5a300000 kernel32!FreeLibraryAndExitThread+40 5a300000 00000102 00000000 w3tp!THREAD_MANAGER::ThreadManagerThread+59 134c7078 00000000 00000000 kernel32!BaseThreadStart+34 5a301d70 134c7078 00000000 -- Edit bug report at http://bugs.php.net/?id=46950&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46950&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46950&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46950&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46950&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46950&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46950&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46950&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46950&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46950&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46950&r=support Expected behavior: http://bugs.php.net/fix.php?id=46950&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46950&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46950&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46950&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46950&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46950&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46950&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46950&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46950&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46950&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46950&r=mysqlcfg
