What steps will reproduce the problem?

Run the attached files.

With go tip you can run directly. With go release you'll need to pre-compile the C/C++
code and link it.

What is the expected output?

300 C'Hello';

What do you see instead?

Sometimes something like:

1 CC'Hello';'Hello';
1
298 C'Hello';

Which compiler are you using (5g, 6g, 8g, gccgo)?

go (default)

Which operating system are you using?

Mac OS X 10.8.4 (darwin amd64)

Which version are you using?  (run 'go version')

go version devel +21a81bde7dc9 Wed Aug 28 09:40:08 2013 +1000 darwin/amd64
go version go1.1.1 darwin/amd64

Please provide any additional information below.

This doesn't happen every time. You have to run the above code a few dozen times before
you get the unexpected output. I have a full library where I was getting this almost
every time. The sample seems to be doing it less frequently for some reason.
