Since I had stripped my httpd, I had to recompile to generate a binary that could be debugged.  Somewhere in the process, the problem vanished; I'm seeing phpinfo() just fine now.  Sorry for any trouble.

-----------

Problem:

I run the server module version of php.  Just upgraded from Apache 1.3.1 / php 
3.0.3 to Apache 1.3.3 / php 3.0.6.  phpinfo() worked fine before, now it makes 
Apache dump core.  Everything else seems to be working fine.  

php config:

--with-apache=/home/drury/apache_1.3.3 --with-gd=no --with-msql=/hom e/drury/msql 
--enable-debug --with-exec-dir=/home/drury/bin --enable-track-vars= yes 
--with-config-file-path=/home/drury/apache/etc --enable-url-includes 
--enable-memory-limit --enable-magic-quotes

Apache config:

--prefix=/home/drury/apache --disable-module=userdir --enable-module=info 
--enable-module=rewrite --enable-module=speling --enable-module=mime_magic 
--enable-module-log_referrer=yes --enable-module-log_agent=yes 
--activate-module=src/modules/php3/libphp3.a

php.ini:

[same as php.ini-dist]

You probably need the ouput of some diagnostic routine to see what's going on 
here.  I'll gladly supply whatever you need, but will need a guidance on how to 
produce it.  For instance, if you need a "backtrace," please give me a hint or two 
about how to generate one.  Thanks.
