I'm quite incredulous that someone else has so recently noticed such a
similarly esoteric problem in flog.
The following is my case:

dking1@SDGL07L3AED1G $ cat foo.rb
#
=begin
=end
dking1@SDGL07L3AED1G $ ruby foo.rb
dking1@SDGL07L3AED1G $ flog foo.rb

dking1@SDGL07L3AED1G $ gem list flog
flog (2.5.0)

And the plot thickens (same ruby & flog versions):

dking1@SDGL07L3AED1G $ cat foo.rb
=begin
=end
dking1@SDGL07L3AED1G $ ruby foo.rb
dking1@SDGL07L3AED1G $ flog foo.rb
     0.0: flog total
     0.0: flog/method average


Thoughts?
