#20021 [Fbk->Opn]: core when execute phpinfo()

ID: 20021 User updated by: scalero@datadec.es Reported By: scalero@datadec.es -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: tru64 v5.1 PHP Version: 4.2.3 New Comment: Definitively gdb not run correctly under tru64 v5.1. In any case, I try compile php with other options: - Without "oci8" --> I obtain the core - Without "ldap" --> OK!!! - With oracle provided ldap --> Not compile The problem is the ldap library "ldap_sdk" provided by Netscape, but I use Netscape directory server. The ldap funtions that I use in my scripts works OK and only phpinfo() crashes. I don´t understand it... Previous Comments: ------------------------------------------------------------------------ [2002-10-24 12:26:16] sniper@php.net From the howto for generating backtraces: "Run httpd -X under gdb with something like: # gdb /usr/local/apache/sbin/httpd (gdb) run -X Then use your web browser and access your server to force the crash. You should see a gdb prompt appear and some message indicating that there was a crash. At this gdb prompt, type: (gdb) bt " Can you try this? Also, try compiling PHP without --with-oci8. If no crash happens, then make --with-ldap to use the oracle provided ldap by passing it the same path as for oci8. And use the latest snapshot for these tests! ------------------------------------------------------------------------ [2002-10-24 03:57:44] scalero@datadec.es When I execute gdb on de core obtain: /usr/local/bin/gdb /usr/internet/httpd/bin/httpd /usr/internet/httpd/core GNU gdb 5.2.1 Copyright 2002 Free Software Foundation, Inc.

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. --- Please read these instructions again and try the method of running httpd under gdb. Also, try compiling PHP without --with-oci8. If no crash happens, then make --with-ldap to use the oracle provided ldap by passing it the same path as for oci8. ------------------------------------------------------------------------ [2002-10-23 01:52:13] scalero@datadec.es I rebuild Apache with: 'LDFLAGS=-lpthread', when I execute ldd httpd: Main => httpd libpthread.so => /usr/shlib/libpthread.so libm.so => /usr/shlib/libm.so libc.so => /usr/shlib/libc.so libexc.so => /usr/shlib/libexc.so And the 'ldap_sdk' are the LDAP libraries of Netscape, I use PHP for access a LDAP directory. ------------------------------------------------------------------------ [2002-10-22 12:30:46] sniper@php.net Forgot to mention this: On some systems you need to have apache httpd also linked with libpthread.so when PHP is linked with oci8.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
