Not on my machine! I'm using the latest CVS version but there
have been no changes to the engine since the 3.1.10 release.

I assume you're talking about the D5 dragon.

gnugo -T shows this in cyan (dead) and we can confirm this as
follows:

address@hidden freedom]$ gnugo --quiet -l [file] -L63 --decide-dragon D5
finished examine_position
D5 can be attacked at C8 (4 variations)
D5 cannot be defended (4 variations)

Is it possible this is a platform dependent problem?

A statement like ``3.1.10 scoring is also messed up'' is not a
good bug report. Please give a reproducible example.
