This bug is similar to 18701 and 15439, but those bugs never reported backtraces or have been full resolved.

The ns-httpd process crashes and core dumps as follows:

26/Oct/2002:14:28:05] catastrophe (12480): Server crash detected (signal SIGBUS)
[26/Oct/2002:14:28:05] info (12480): Crash occurred in NSAPI SAF php4_execute
[26/Oct/2002:14:28:05] info (12480): Crash occurred in function php_register_variable_ex from module

when loading any php script. The php script that reproduces this is:

bash-2.05$ more phpinfo.php 
<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <?php echo "Hello World<p>"; ?>
 <? phpinfo(); ?>
 </body>
</html>

Recompiled with the latest snap (php4-200210261200) and with Forte 7 compilers (previous was with gcc 2.95.3) . Similar crash, here is the dbx backtrace:

As much as I don't like nsapi, we can't have it not working for 4.3.0 release... since it has historically worked (sometimes).
 [2002-11-16 13:09 UTC] cjs at goosenest dot org 
Updated to iPlanet-WebServer-Enterprise/6.0SP5 and tried 
php4-STABLE-200211161630. Same crash, no change.


[16/Nov/2002:14:07:33] catastrophe (22765): Server crash detected (signal SIGBUS)

 [2002-11-21 22:57 UTC] cjs at goosenest dot org 
Added 4.3.0-dev to version.
 [2003-01-02 16:52 UTC] cjs at goosenest dot org 
Tested and reverified with 4.3.0 release.
 [2003-03-13 13:00 UTC] thetaphi@php.net

For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

NSAPI register_server_variables completely redesigned. Should work now.
