#36234 [Opn->WFx]: segfault when testing property of an overloaded class in switch a statement

ID: 36234 Updated by: sniper@php.net Reported By: matt dot flaherty at hildebrand dot co dot uk -Status: Open +Status: Wont fix Bug Type: Reproducible crash Operating System: SUSE LINUX 10.0 (i586) PHP Version: 4.4.2 New Comment: As there is no maintainer and any serious OO stuff should be done with 5.1 anyway -> wont fix. (there are more important things to fix than hacks like this) Previous Comments: ------------------------------------------------------------------------ [2006-02-13 19:38:18] andrei@php.net I am not maintaining this anymore. ------------------------------------------------------------------------ [2006-02-13 15:53:49] matt dot flaherty at hildebrand dot co dot uk Thank you for this. I'm aware that the OO implementation in PHP5 is very different and I intend to use 5 for any serious OO development from now on. However, there is a project I'm working on which requires PHP 4 and needs a drop-in replacement for the PEAR DB libraries within a third-party framework. As support for PHP 4 is still a going concern I decided to raise this ticket. Since posting this bug report, I have also encountered the same problem in PHP 4.3.11. Thank you again for your response. ------------------------------------------------------------------------ [2006-02-11 13:19:50] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-01-31 23:51:27] judas dot iscariote at gmail dot com Program received signal SIGSEGV, Segmentation fault. 0x0000000000417258 in overload_get_property (property_reference=0x7fffffe61af8) at /home/cristian/php-src/ext/overload/overload.c:363 363 if (Z_TYPE_P(overloaded_property) == OE_IS_OBJECT) { (gdb) bt #0 0x0000000000417258 in overload_get_property (property_reference=0x7fffffe61af8) at /home/cristian/php-src/ext/overload/overload.c:363 #1 0x00000000004e9c01 in get_overloaded_property (T=0x7fffffe61ae0) at /home/cristian/php-src/Zend/zend_execute.c:970 #2 0x00000000004e8327 in _get_zval_ptr (node=0x6a6bd0, Ts=0x7fffffe614c0, should_free=0x649c10) at /home/cristian/php-src/Zend/zend_execute.c:93 #3 0x00000000004f2503 in zend_switch_free (opline=0x6a6ba8, Ts=0x7fffffe614c0) at /home/cristian/php-src/Zend/zend_execute.c:236 #4 0x00000000004efe54 in execute (op_array=0x6978d0) at /home/cristian/php-src/Zend/zend_execute.c:2053 #5 0x00000000004d5cf5 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /home/cristian/php-src/Zend/zend.c:934 #6 0x0000000000498774 in php_execute_script (primary_file=0x7fffffe64750) at /home/cristian/php-src/main/main.c:1753 #7 0x00000000004f50eb in main (argc=2, argv=0x7fffffe648b8) at /home/cristian/php-src/sapi/cli/php_cli.c:830 ./sapi/cli/php -v PHP 4.4.3-dev (cli) (built: Jan 31 2006 19:48:51) (DEBUG) ------------------------------------------------------------------------ [2006-01-31 18:30:29] matt dot flaherty at hildebrand dot co dot uk Almost forgot.
