I have another Coverity related question ... what is one expected to do
with issues like this one?

40 FORWARD_NULL /src2/git/pcp/src/pmlogger/<stdout> yy_get_next_buffer
UNINSPECTED

I assume this is found in the bison output file, but there is no context
or line number to help isolate the "issue".
