Thanks for looking into this.  What you are seeing is odd and I have no
explanation.  Can you try building the test with GOCFLAGS="-g -O2
-fgo-dump-ast" which should give you a .go.dump.ast file in the working
directory.  Attach that file.  That will help show whether the problem is in
the Go frontend or whether the missing assignments are being removed by the GCC
middle-end somewhere.  Thanks.
