Bug #68862 [Opn->Fbk]: crash in php5ts.dll

Edit report at https://bugs.php.net/bug.php?id=68862&edit=1 ID: 68862 Updated by: ab@php.net Reported by: chr dot schubert at gmx dot de Summary: crash in php5ts.dll -Status: Open +Status: Feedback Type: Bug Package: Reproducible crash Operating System: Windows 7 / Windows 2008 R2 PHP Version: 5.5.20 Block user comment: N Private report: N New Comment: 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. It's hard to say what happens under the carpet yet. It would rock if you could extract some reproduce snippet from your script. Also, you could try some of the latest 5.5 snapshots http://windows.php.net/downloads/snaps/php-5.5/ . Thanks.

The webserver is Apache 2.4.10 downloaded from https://www.apachelounge.com/download. It is used together with PHP 5.5.20 (obtained from http://windows.php.net/download#php-5.5-ts-VC11-x86) installed as Apache 2.0 Handler (= Output in field Server API from phpinfo()). When a php script is accessed from different Clients via the web Server, it does not take long (~30seconds) until I receive an "Access Violation error 0xc0000005" (This is if I run httpd -X. Otherwise corresponding log entries occur) After the Crash the backtrace points at varying positions in php5ts.dll. Only one module is being used by my php: php_oci8_11g.dll I tried both the x86 and x64 Versions on multiple computers. It seems to me that the x86 Version takes a bit longer to Crash. Any help is greatly appreciated. Changes made to php.ini (compared to php.ini-dist): extension=php_oci8_11g.dll date.timezone = "Europe/Berlin" date.default_latitude = 51.248532 date.default_longitude = 6.704677 Test script: --------------- Unfortunately, I cannot publish the php script we run. However, I am happy to try out any suggestions. I can only publish how the Clients Access the webserver: <html> <head> <meta http-equiv="refresh" content="0"> </head> <body> <iframe src="http://webserver/script.php?event=PING" /> </body> </html> Expected result: ---------------- No Crash ;-) Actual result: -------------- ----------------------------------------- Visual Studio Backtrace 1: ----------------------------------------- ntdll.dll!77112d47() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] kernel32.dll!754cc484() kernel32.dll!754cc484() msvcr110.dll!611edac2() > php5ts.dll!timelib_time_dtor(timelib_time * t=0x0759a818) Line 84 + 0x12 bytes C php5ts.dll!php_format_date(char * format=0x05e75e10, int format_len=3, long ts=1421756704, int localtime=1, void * * * tsrm_ls=0x057ae6e0) Line 1251 + 0x8 bytes C php5ts.dll!php_date(int ht=1, _zval_struct * return_value=0x05e75b28, _zval_struct * * return_value_ptr=0x00000000, _zval_struct * this_ptr=0x00000000, int return_value_used=1, void * * * tsrm_ls=0x057ae6e0, int localtime=1) Line 1227 C php5ts.dll!zif_date(int ht=1, _zval_struct * return_value=0x05e75b28, _zval_struct * * return_value_ptr=0x00000000, _zval_struct * this_ptr=0x00000000, int return_value_used=1, void * * * tsrm_ls=0x057ae6e0) Line 1356 + 0x1f bytes C php5ts.dll!zend_do_fcall_common_helper_SPEC(_zend_execute_data * execute_data=0x00270000, void * * * tsrm_ls=0x075a7ad0) Line 551 C php5ts.dll!execute_ex(_zend_execute_data * execute_data=0x05e62064, void * * * tsrm_ls=0x057ae6e0) Line 363 + 0xf9 bytes C php5ts.dll!zend_execute(_zend_op_array * op_array=0x05ded728, void * * * tsrm_ls=0x0000002c) Line 388 + 0x1a6 bytes C php5ts.dll!zend_execute_scripts(int type=262983856, void * * * tsrm_ls=0x00000008, _zval_struct * * retval=0x00000001, int file_count=0, ...)
