            Bug ID: 57477
           Summary: mod_macro AH00052: child pid $pid exit signal Floating
                    point exception
           Product: Apache httpd-2
           Version: 2.4.10
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: All
          Assignee: bugs@httpd.apache.org
          Reporter: ohauer@gmx.de

I have a system with many similar AJP backends, defining them one by one
(without mod macro) this works fine, defining them with mod_macro the log fills
up with AH00052 errors even only one client backend is defined with "Use ..."


<Macro AJP_REV_CLIENT $path $IP>
    <Proxy balancer://$path>
        BalancerMember ajp://$IP:8009/testproject keepalive=On ttl=60
    </Proxy>
    <Location /$path>
        ProxyPass        balancer://$path
        ProxyPassReverse balancer://$path
        RequestHeader set X-company-context /$path
        Header edit Set-Cookie "^(.*; Path=)/testproject/?(.*)" $1/$path/$2
    </Location>
</Macro>

Use AJP_REV_CLIENT username1 4.3.2.1
Use AJP_REV_CLIENT username2 4.3.2.2
Use AJP_REV_CLIENT username3 4.3.2.3
