[Bug 57745] New: httpd exits 1 with no stderr when proxy_balancer_module is enabled

https://bz.apache.org/bugzilla/show_bug.cgi?id=57745

            Bug ID: 57745
           Summary: httpd exits 1 with no stderr when
                    proxy_balancer_module is enabled
           Product: Apache httpd-2
           Version: 2.4.12
          Hardware: Macintosh
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy_balancer
          Assignee: bugs@httpd.apache.org
          Reporter: john@smadness.com

httpd exits 1 quickly after launch with no stderr when proxy_balancer_module
(and proxy_module) is enabled.  This makes it extremely difficult to determine
what the problem is.

In general, I'm trying to enable proxies and use proxy_balancer_module. 
However, even though mod_proxy loads fine, whenever I uncomment loading
mod_proxy_balancer.so, httpd exits with 1 and no stderr.

Built from source:

apr-1.5.1
apr-util-1.5.4 --with-ldap

httpd-2.4.12:
./configure --prefix=/usr/local/apache2 --enable-mods-shared=all --enable-ldap
--enable-auth-ldap --enable-authnz-ldap --enable-ssl --with-ldap
--with-apr=/usr/local/apr/bin/apr-1-config
--with-apr-util=/usr/local/apr/bin/apu-1-config

Mostly using the default .conf, the extra module loading is in a different
.conf under sites, reproduced below.

Yes, adding in these two modules allows httpd to stay alive:

LoadModule slotmem_shm_module modules/mod_slotmem_shm.so
LoadModule slotmem_plain_module modules/mod_slotmem_plain.so

It would be great if a debug / error message could be added to this codepath. 
I did not even see the message "Failed to lookup provider 'shm' for 'slotmem':
is mod_slotmem_shm loaded??" in the debug log.

Also, I should have included the debug output:

I'm not sue why you don't see it. Are you sure you're looking at the main/base
error log? I see you didn't attach _any_ erorlog messages.

Right, they shouldn't. But the globally defined errorlog should (and does) on
other platforms.

--- Comment #5 from john gale <jo...@smadness.com> ---
That's because there are no error log messages when I launch httpd.  When
launching automatically through launchd (on Mac OS X) I modified the plist to
spit stdout and stderr to a log.  Without including the slotmem modules,
loading / starting the launchd plist does not output anything to the stdout or
stderr log;  system log shows something like "httpd exited with 1. Relaunching
in 10s..."

When running through command line 'sudo httpd -e debug -X', I get some debug
module output as pasted above, but no errors as far as I can see.  The
individual sites' access and error logs are not populated at all, I'm assuming
because httpd never loads fully before exiting.
