Bug #17058 Updated: child pid XXX exit signal Segmentation Fault (11)

ID: 17058 Updated by: alan_k@php.net Reported By: karyn.joseph@teradyne.com Status: Open Bug Type: Reproducible crash Operating System: Solaris 2.7 PHP Version: 4.2.0 New Comment: if you need to check a php binary to see how it was configured apart from <? phpinfo() ?> strings libphp4.so | grep configure I did notice that your apache modules directory was this /opt/apache_1.3_64/libexec/libphp4.so and you used apxs from here - "--with-apxs=/opt/apache/bin/apxs" I presume they are the same install of apache? Previous Comments: ------------------------------------------------------------------------ [2002-05-08 16:08:00] karyn.joseph@teradyne.com I thought it was. I'm new to php, so am not sure what else I could do to change the install. I'll try to recompile php again and remove the previous install. Once installed, how can I tell if the correct modules are loaded or not? Thanks, Karyn ------------------------------------------------------------------------ [2002-05-08 16:04:38] mfischer@php.net The line #0 0xfed00178 in ?? () from /opt/apache_1.3_64/libexec/libphp4.so tells me the debugger can't find the symbols which means that this binary doesn't have the debug symbols which are normally generated when compiling with --enable-debug Have you made sure the right binary is installed and loaded in the debugger? ------------------------------------------------------------------------ [2002-05-08 16:00:36] karyn.joseph@teradyne.com It was compiled with --enable-debug. Here's the config. Did I do something incorrectly?: cat config.nice #! /bin/sh # # Created by configure "./configure" \ "--with-mysql" \ "--prefix=/opt/php-4ORC1" \ "--enable-debug" \ "--with-apxs=/opt/apache/bin/apxs" \ "$@" Thank you for the help. Karyn ------------------------------------------------------------------------ [2002-05-08 15:57:38] mfischer@php.net Now that we know it crashes in libphp4.so you need to recompile PHP with --enable-debug in other to get more information where it exactly crashed. ------------------------------------------------------------------------ [2002-05-08 15:43:56] karyn.joseph@teradyne.com Backtrace information ...
