Apache 1.3.12, mod_ssl 2.3.6, mod_perl 1.2.4 and php4.0.1pl2 are all compiled/installed.

mod_perl:

# perl Makefile.PL EVERYTHING=1 DO_HTTPD=1 PREP_HTTPD=1 USE_APACI=1

mod_ssl:

# ./configure --with-apache=../apache-1.3.12

Apache:

./configure --enable-module=ssl --enable-shared=max --activate-module=src/modules/perl/libperl.a --prefix=/www

[ now the Apache is installed ]

PHP:

./configure --with-apxs=/www/bin/apxs --with-mysql=/opt/mySQL/

-------------------------------------------

After Apache is started, *any* request will generate segmentation fault.

GDB output:
[root@x tmp]# gdb httpd

(gdb) r -X
Starting program: /www/bin/httpd -X

does this happen with php4.0.3pl1?
 [2000-12-05 01:57 UTC] sniper@php.net 
This should be fixed in CVS. 
Please try latest snapshot or wait for PHP 4.0.4 to be released. 
If problem still exists with snapshot or PHP 4.0.4, reopen this bug report.
