 So it looks like gccgo reads the expression as
 
   (*pg)(0)


I meant

-  (*(g))(0)

 while golang reads it as
 
   *(pg(0))


-  *((g(0)))

I don't think there is any parsing issue with the omitted error on line 5. 
It's just that gccgo converts *x to x for any x, and forgets to test that x
must be addressable.
