Bug #15778 Updated: Segmentation Fault with iPlanet module on php4_init

ID: 15778 Updated by: lbalbalba@hotmail.com Reported By: lbalbalba@hotmail.com Status: Open Bug Type: Reproducible crash Operating System: AIX 4.3.3 PHP Version: 4.1.2 New Comment: Compiled php 4.1.2 using IBM's C for AIX Compiler v4.4.0.3 instead of using GCC, and verified that with the different compiler the bug still existed. Previous Comments: ------------------------------------------------------------------------ [2002-03-04 06:55:10] lbalbalba@hotmail.com Bug verified and still present in snapshot "php4-200203040000" on AIX 4.3.3 and iPlanet 4.1 ------------------------------------------------------------------------ [2002-03-01 12:27:31] lbalbalba@hotmail.com Ok, as another test, Ive tried to compile PHP 4.1.2 on the same AIX 4.3.3 box, but now as an Apache 1.3.22 DSO module, and that seems to work just fine. And since ive got the same php version (4.1.1 & 4.1.2) in combination with the same iPlanet version (4.1) running correctly on Linux, I guess this means that this only occurs on this specific combined setup: AIX 4.3.3 iPlanet 4.1 PHP 4.1.1 & 4.1.2 (at least, maybe other versions too) ------------------------------------------------------------------------ [2002-02-28 06:13:51] lbalbalba@hotmail.com As a test, Ive tried compiling the same version of PHP in combination with the same version of iPlanet on my linux system, and everything seems to work fine on my linux box. So I guess this only occurs in combination with AIX. ------------------------------------------------------------------------ [2002-02-28 06:04:27] lbalbalba@hotmail.com When I compile PHP as an iPlanet module, the httpd server crashes on loading the module (php4_init) with a signal 11/segmentation fault. I get the same behaviour with php 4.1.1 and with 4.1.2. (output below is from 4.1.2) When compiling as a commandline executable, everything seems to work fine though, so I guess its a problem with iPlanet and maybe in combination with AIX 4.3.3 and shared libraries. I compiled using GCC, not AIX's 'native' compiler. If more information is needed to address this issue, please let me know. Please be aware though, that even though I am decently skilled in *nix administration, I have no programming or debugging skills, so please provide 'idiot instructions' ;) The configure line I used: ./configure --with-nsapi=/appl/netscape4/server4 --prefix=/appl/php -exec-prefix=/appl/php --enable-debug The output of gdb (bt): # gdb /appl/netscape4/server4/bin/https/bin/ns-httpd /appl/netscape4/server4/https-splu9029/config/config/core GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.
