Hi Jie,

At the moment, I'm still on the fence of whether this is a supportable use
case (in the faux-handler for the modperl alt protocol example.)

If it is not, the fix is to drop the test from modperl.

Otherwise, the fix is also straightforward, I can provide hints, but you
can cause the fault by changing the domain name in the test case config
from example 'hostname' to example 'ip addr'.  The offending code is in the
backtrace.  Both ip and host lookups would test if the useragent_addr is
null, and use the corresponding lookups from the conn_rec.

I sort of expect the modperl test to continue to be broken because the
req_rec simply has not been fully initialized... it is not until the entire
read_req hook phase is complete that all these req_rec field members have
meaningful values.

But if enough folks agree we can fix the lookup to refer to the conn_rec
values until useragent_addr is initialized.
