#20388 [Fbk->Csd]: Segmentation Fault

ID: 20388 User updated by: mike.hall@opencube.co.uk Reported By: mike.hall@opencube.co.uk -Status: Feedback +Status: Closed Bug Type: *XML functions Operating System: FreeBSD 4.6 PHP Version: 4.2.3 New Comment: I installed xdebug, then the software stopped crashing! I took xdebug off again and it still isn't crashing. Very odd. Previous Comments: ------------------------------------------------------------------------ [2002-11-12 12:05:20] derick@php.net it would be cool if you could try the following to see if you're calling recursive functions: 1. Download xdebug from http://xdebug.derickrethans.nl/link.php?url=xdebug100rc1-422-f46 2. enable it in your php.ini file: zend_extension=/path/to/module/xdebug.so and restart your webserver and try the script, or start your command line script. It should give you a warning if you're trying to recursively call functions (with a full trace of all function calls). regards, Derick ------------------------------------------------------------------------ [2002-11-12 11:06:37] mike.hall@opencube.co.uk I tried with http://snaps.php.net/php4-latest.tar.gz and the system is still seg faulting. The strange thing is - I ran exactly the same code for several weeks without trouble. I can look at packaging up the code, but it is part of a very large application. I will try and put something together though. I don't think I am recursively calling any functions though! Backtrace is a little different this time. #0 0x283d9faf in isatty () from /usr/lib/libc.so.4 (gdb) bt #0 0x283d9faf in isatty () from /usr/lib/libc.so.4 #1 0x283da6cd in malloc () from

10:40:51] derick@php.net Hello, I think you're recursivley calling a function somewhere, would it be possible to tar the whole package up so that we can try to reproduce it? Derick ------------------------------------------------------------------------ [2002-11-12 10:40:49] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip and NOT the 'STABLE' ones.. ------------------------------------------------------------------------ [2002-11-12 10:36:23] mike.hall@opencube.co.uk Yes, I tried with php4-STABLE-200211121230 from snaps.
