Not a very useful error... if this is user error, it isn't very obvious
what is wrong.

Actually, I was running 4.0.6 before this upgrade, not 4.1.1, but I did
use the same configuration options that I used from 4.0.6 (I always
save my ./configure options so that I can recreate them).

This is what I am using for my apache configuration:
./configure \
--prefix=/usr/local/apache \
--enable-module=unique_id \
--enable-module=rewrite \
--enable-module=speling \
--enable-module=expires \
--enable-module=info \
--enable-module=log_agent \
--enable-module=log_referer \
--enable-module=so \
--logfiledir=/var/log/apache \
--activate-module=src/modules/php4/libphp4.a \
--enable-module=vhost_alias
This is what I am using for my php configuration:
./configure \
--prefix=/usr/local/php \
--with-apache=../apache_1.3.23 \
--enable-ftp \
--with-xml \
--enable-track-vars \
--with-mysql=/usr/local/mysql \
--with-pgsql=/usr/local/pgsql/ \
--enable-debug \--with-config-file-path=/usr/local/php/lib
also, ran gdb and did a little poking around:

There is nothing here to go on. If you could compile and run 4.1.1 you
can compile and run 4.1.2. Nothing was changed that would cause this
sort of problem. Your strace doesn't even touch anything in PHP.
Check your build options for 4.1.1, compare them to what you are doing
for 4.1.2. I suspect user-error here.
------------------------------------------------------------------------

This is actually php version 4.1.2 (there is no selection for that in
this form). I've compiled a new version of apache 1.2.23 and PHP 4.1.2
and when I try to start apache it dies immediately without any errors
in the error_log or anywhere else. I tried to strace the binary, but
nothing showed up, with --enable-debug on, I get the following:
zend_hash.c(532) : ht=0x081d8860 is already destroyed
zend_hash.c(98) : Bailed out without a bailout address!
in my error log. If I try to do a gdb back trace I get the following:
(gdb) run -X
Starting program: /usr/local/apache/bin/httpd_new -X
Program exited with code 0377.
(gdb) bt
No stack.
When I didn't have --enable-debug compiled in and I attempted to do a
backtrace, I got the following:
F10 key ==> File Edit Search Buffers Windows System Help
Program received signal SIGSEGV, Segmentation fault.
0x28893e in malloc () from /lib/libc.so.6
crap, hold on
exited gdb already :)
I dont like having our webserver down for so long
ok did the bt

Until I can get this working, I am running with the remote root
exploit! Please help, thanks...
