Summary: Opcache extension causes PHP process termination
-Status: Feedback
+Status: Open
Type: Bug
Package: opcache
Operating System: Windows 10
PHP Version: 5.6.15RC1

New Comment:
I have used default php ini configuration. The only diffs:
- Extension path was directed to the same directory as php.exe
- there was enabled only extension:
zend_extension=php_opcache.dll
- opcache settings:
[opcache]
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=0
The PHP was executed via mod_fcgid in apache 2.2.29. Httpd.conf snippet:
LoadModule fcgid_module modules/mod_fcgid.so
AddHandler fcgid-script .php
FcgidWrapper "\"C:/sw/MyQ/php/php/php-cgi.exe\"" .php
AddType application/x-httpd-php .php
FcgidMaxProcesses 20
FcgidMaxRequestsPerProcess 490
# PHP has max_execution_time=300, add 10 here to be sure
FcgidIOTimeout 310
# PHP has 20M, add 1M here to be sure
FcgidMaxRequestLen 22020096
# Fix the opcache bug with tmp path
FcgidInitialEnv TEMP "C:/WINDOWS/TEMP"
FcgidInitialEnv TMP "C:/WINDOWS/TEMP
I executed many requests using utility ab:
ab -n 1000 -6 http://127.0.0.1/test.php
Where the content of test.php was following:
<?php
$sec = 3;
echo "waiting $sec s...";
for($i=0; $i < $sec; ++$i) {
sleep(1);
}
echo "konec<br>";
echo "cekalo se $sec sekund";
phpinfo();
Note: The same behaviour appears even we use our internal php process manager. Our php process
manager is simple tool which preloads php processes, it uses (our implementation of) fast cgi to
communicate with php.

I have tested the listed snapshot, and I have compiled my own relaese binaries from revision
36311ee4fd0ad33735ab0dc02f795b65888ca72d and must announce that the crashing still persists. The
stack is same as in previous step:
php_opcache.dll!accel_startup(_zend_extension * extension) Line 2599 C
php5.dll!zend_extension_startup(_zend_extension * extension) Line 154 C
php5.dll!zend_llist_apply_with_del(_zend_llist * l, int (void *) * func) Line 178 C
php5.dll!zend_startup_extensions(...) Line 175 C
php5.dll!php_module_startup(_sapi_module_struct * sf, _zend_module_entry * additional_modules,
unsigned int num_additional_modules) Line 2312 C
php-cgi.exe!php_cgi_startup(_sapi_module_struct * sapi_module) Line 942 C
php-cgi.exe!main(int argc, char * * argv) Line 1919 C

Thanks for your time.

Thanks for the trace, Petr. Could you please check whether this (or later) snap fixes the issue? http://windows.php.net/downloads/snaps/php-5.6/r22af882/
.
Otherwise I'd need your ini settings and maybe some description how to reproduce this.
Thanks.

Thanks for the report. This looks like something else however, especially as you don't mention
the "base address". Could you please show the backtrace? This info can help on getting it

Thanks.
