command tag logging

I just installed a compiled from src 8.3.11.  I usually include %i, command tag,
in the log_line_prefix setting.  This causes some spewage I'd not seen before
on connection received lines as if it is dumping the environment:

I took the $i out of the mix for now:

Is this repeatable elsewhere?  Thanks.
