Hello,

On our server running Apache 1.3.11 we cannot use PHP 4.0.6, since loading the libphp4.so crashes Apache at startup w/o giving any clue about the problem:

# /etc/init.d/httpd start
Segmentation Fault - core dumped
/pub/httpd/sbin/apachectl startssl: httpd could not be started
# 

GDB backtrace:
-----------
(gdb) bt
#0  0xef5ce544 in strrchr ()
#1  0x22e0c in ap_add_module ()
#2  0x230e4 in ap_add_loaded_module ()
#3  0x1aa58 in load_module ()
#4  0x238d8 in invoke_cmd ()
#5  0x24794 in ap_handle_command ()
#6  0x24874 in ap_srm_command_loop ()
#7  0x24efc in ap_process_resource_config ()
#8  0x25b04 in ap_read_config ()
#9  0x34b54 in main ()
(gdb) 

As soon as the AddModule and LoadModule directives for PHP4 are removed from httpd.conf, the Server can start up w/o problems.


PHP configuration:
-------------
./configure --prefix=/usr/pack/php-4.0.6-ft
               --with-mysql=/pub/mysql/3.22.32/
               --with-pgsql=/pub/postgresql/7.0.2
               --enable-track-vars
               --with-db
               --with-ndb
              --with-apxs=/pub/apache/1.3.11-nosuexec/bin/apxs


The identical Module works w/o problems on an other Sun Server running the same Apache (1.3.11, identical installation).

Server information (uname -a):
----------------------
The server where Apache crashes:
  SunOS XXXXX 5.6 Generic_105181-17 sun4u sparc SUNW,Ultra-4

The server w/o problems
  SunOS YYYYY 5.6 Generic_105181-21 sun4u sparc SUNW,Ultra-250


Thank you very much in advance for any help

Build with debug symbols please so we can have a real backtrace.  You are also way behind with your Apache version.  Current version is 1.3.22.

Upgrade to 1.3.22, .11 has some problems, and AFAIK it was never released to the public.
This should solve the crashes (it seems like it is crashing in apache to me anyways).

regards,
Derick

Absolutely identical backtrace even when configured with --enable-debug.

It works in the identical setup like a charm on an other machine (same binaries!), what could be the reason, that it doesn't work here?

btw: I'm still looking for those admins who can always keep up with the newest version of all packages (about 280 packages at our site...)
 [2002-01-16 14:19 UTC] rasmus@php.net 
Well, since the crash is in Apache, it is Apache you need to build with debug symbols, not PHP.
 [2002-01-16 14:25 UTC] thommen at inf dot ethz dot ch 
No way to recompile Apache 1.3.11 here.  Nobody kept the sources :-(.  I'll drop that case and try with an Apache upgrade.

Thank you very much anyway
