Bug #78125 [Asn]: Persistent php-cgi.exe access fault

Edit report at https://bugs.php.net/bug.php?id=78125&edit=1 ID: 78125 User updated by: aschmidt at anamera dot net Reported by: aschmidt at anamera dot net Summary: Persistent php-cgi.exe access fault Status: Assigned Type: Bug Package: opcache Operating System: Win x64 PHP Version: 7.2.21-dev Assigned To: cmb Block user comment: N Private report: N New Comment: PS: The phpinfo() error results in php-cgi ending with Windows error ERROR_INVALID_DATA (0x8007000D) Previous Comments: ------------------------------------------------------------------------ [2019-06-14 21:21:53] aschmidt at anamera dot net Problem 1 (persistent): <?php phpinfo( $_GET[ 'i' ] ?? INFO_ALL ); ?> Will work in IIS for all INFO_* values EXCEPT for INFO_MODULES. phpinfo( 8 ) will fail in PHP. However, opcache.php will work fine - and my own scripts seem to work. Also, executing same phpinfo() in CLI runs without apparent problems. Problem 2 (one-time): Initially, after installing 7.2.21-dev, I had restarted the PHP-CLI background application is running first (as a Windows Service) and THEN IIS PHP. This result in FASTCGI crashing with these event log entries occur: Zend OPcache, Event ID 2: Unable to open base address file The system cannot find the file specified. Problem 3 (persistent): If I REBOOT Windows Server, then IIS will start and run (with the exception of phpinfo() ), BUT, I am now unable to start the PHP-CLI service. If I STOP IIS, THEN I can start the PHP-CLI service. This problem can be circumvented with opcache.enable_cli=0. In summary: There STILL appears to be a concurrency problem with OPcache FastCGI and CLI active at the same time. And I there is a problem with OPcache and phpinfo(8) in IIS. ------------------------------------------------------------------------ [2019-06-14 18:07:49] cmb@php.net Can you please try the latest snapshot[1]? [1] <https://windows.php.net/downloads/snaps/php-7.2/r28808ca/> ------------------------------------------------------------------------ [2019-06-09 12:38:10] aschmidt at anamera dot net The problem occurs when a minimal "phpinfo();" script is executed in IIS. However it APPEARS to only occur when both a CLI and a FastCGI application are running at the same time under 7.2.19 with OpCache enabled. I have a CLI application running as a Windows Service. After upgraded to 7.2.19 I first started IIS to get my site running again, but then the Windows Service would not start the CLI app. Baffled, I rebooted the server, which automatically starts the service. I confirmed that NOW the service WAS running. I then started IIS by hand - and whenever I run a basic phpinfo() THAT would now crash. I then stopped the service and IIS, reverted to 7.2.18 (without rebooting) and was aber to start both without problems. With that knowledge, I downloaded 7.2.19 one more time (in case of any download errors), copied it over 7.2.18 again, started the service by hand, and reproduced the IIS error. Finally, I disabled OPcache in 7.2.19 and NOW IIS was successfully running FastCGI in parallel with the CLI Service. Here the most relevant of my PHP.INI settings: precision = 14 zlib.output_compression = Off serialize_precision = -1 zend.enable_gc = On report_memleaks = On auto_globals_jit = On enable_dl = Off zend.assertions = -1 opcache.enable=1 opcache.enable_cli=1 opcache.memory_consumption=256 opcache.interned_strings_buffer=16 opcache.max_accelerated_files=3907 opcache.revalidate_freq=30 ;(per IIS .user.ini: opcache.revalidate_freq=0 ) opcache.enable_file_override=1 opcache.log_verbosity_level=2 opcache.file_cache=C:\Windows\Temp\PHP\OpCache opcache.file_update_protection=10 cgi.force_redirect=0 cgi.fix_pathinfo=1 fastcgi.impersonate=1 fastcgi.logging=1 [ExtensionList] extension=php_mysqli.dll extension=php_mbstring.dll extension=php_gd2.dll extension=php_gettext.dll extension=php_intl.dll extension=php_curl.dll extension=php_exif.dll extension=php_xmlrpc.dll extension=php_openssl.dll extension=php_soap.dll extension=php_pdo_mysql.dll extension=php_pdo_sqlite.dll extension=php_imap.dll extension=php_tidy.dll extension=php_xsl.dll extension=php_yaml.dll extension=php_fileinfo.dll extension=php_componere.dll extension=php_win32service.dll zend_extension=php_opcache.dll [XDebug] ; Must be loaded after OpCache ! zend_extension = "C:\Program Files\PHP\v7.2\ext\php_xdebug-2.7.2-7.2-vc15-nts-x86_64.dll" xdebug.coverage_enable=0 [PHP_WINCACHE] extension=php_wincache.dll wincache.reroute_enabled=1 wincache.fcachesize=32 wincache.maxfilesize=512 session.save_handler=wincache ------------------------------------------------------------------------ [2019-06-08 07:32:55] krakjoe@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2019-06-07 19:45:34] aschmidt at anamera dot net Description: ------------ After upgrading from 7.2.18 to 7.2.19: "php-cgi.exe - Application Error : The instruction at 0xa522405a referenced memory at 0xffffffff.
