From: petr dot maly at remotehost dot cz Operating system: Windows 10 PHP version: 7.0.11 Package: COM related Bug Type: Bug Bug description:php-cgi.exe is crashing while the script execution is being finalized Description: ------------ When the script uses COM object several times and all the statements are executed, php-cgi.exe crashes while it is shutting down. This causes that Apache returns error 5xx, the script code is executed correctly. The crashing happens randomly. I was inspecting the code of php_com_dotnet extension and I found that the php crashes while it is trying to call destructor on function object: com_handlers.c(237:246): static void function_dtor(zval *zv) { zend_internal_function *f = (zend_internal_function*)Z_PTR_P(zv); zend_string_release(f->function_name); if (f->arg_info) { efree(f->arg_info); } efree(f); } The destructor crashes because f->function_name is NULL (sometimes), therefore zend_string_release is unable to access member variables. Suggested fix: static void function_dtor(zval *zv) { zend_internal_function *f = (zend_internal_function*)Z_PTR_P(zv); if (f->function_name != NULL) { zend_string_release(f->function_name); } if (f->arg_info) { efree(f->arg_info); } efree(f); } Best Regards, Petr Maly -- Edit bug report at https://bugs.php.net/bug.php?id=73241&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73241&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73241&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73241&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73241&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73241&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73241&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73241&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73241&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73241&r=support Expected behavior: https://bugs.php.net/fix.php?id=73241&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73241&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73241&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73241&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73241&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73241&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73241&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73241&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73241&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73241&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73241&r=mysqlcfg
