I have the same problem after I installed the latest version of go. And I 
suspect type conversion problems.

The release notes (http://golang.org/doc/devel/release.html) of the 2010-06-09 
release say:

The type checking rules around assignments and conversions are simpler but more
restrictive: assignments no longer convert implicitly from *[10]int to []int
(write x[0:] instead of &x), and conversions can no longer change the names of
types inside composite types.

It would be great if someone could have a look and fix that problem.

I am having the same problem.  I changedline # 382 from

copy(&v.Data8, b)

to this

copy(v.Data8[0:], b)

per the specification and now it compiles.
