You are misunderstanding what's happening here. GNU Go
isn't trying to read an sgf file. Indeed, your file has
already been read and parsed. At the point of the crash
GNU Go is trying to create one. In GNU Go 2.6, this
code works correctly and if gnugo -l [filename] --score last
is called without specifying an analyzer file it just 
reports the score. 

However changes to the sgf code in 2.7.132 broke this.
2.7.131 was the last version which doesn't crash on
--score last or --score [movenum].

We haven't been using the analyzer file but there is still
an evident demand for --score. The enclose patch fixes
these options by simply backing out all the sgf stuff and
just reporting the answer to stdout.
