 When I use php 3.0.12 with Apache 1.3.9 it crashes when I put a VirtualHost command in the config file.
 If I leave out the VirtualHost Apache starts fine. If I put the VirtualHost in and remove PHP Apache starts fine.
 If I roll back to Apache 1.3.6 it starts fine.

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior.  In order for PHP to
; read it, it must be named 'php.ini'.  PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory.  The
; path in which the php.ini file is looked for can be overriden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple.  Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future (they probably won't).
;
; Options are specified using the syntax key = value or key = "complex value".
; Key names are *case sensitive*.  foo = bar is different from FOO = bar.
; 'value' can be any number, word or keyword (keywords are On, Off, True,
; False, Yes and No, and are case insensitive).
; 'complex value' can be just about anything, expcept for " and a newline
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

I bet you didn't recompile PHP against Apache-1.3.9.  If you use the PHP DSO compiled against
Apache-1.3.6 and LoadModule it into Apache-1.3.9 this is exactly what I would expect to see.
Make sure you do a full configure; make; make install of Apache-1.3.9 so you get the updated
apxs script from Apache-1.3.9 installed and then do a make clean in your PHP src directory and
do a full configure; make; make install of PHP.

Ok... at first I thought you might be right about the apache 1.3.6 thing. So I carefully reproduced the problem. I did some trouble shooting and found that it only happens with the following combination:

 apache 1.3.9
 one or more VirtualHost declarations
 --with-mycrypt

 and i looked at the code using the backtrace as a reference and it is crashing when it tries to close the php.ini file.

Thank you for taking the time to report a problem with PHP.
Unfortunately, PHP 3 is no longer supported. Please download
the latest version of PHP 4 from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
