[antlr-interest] Bug report; generated C(++) code inappropriately initialises non-primitive return values

[Richard Thrippleton]

When I have a rule of the form

"rule returns [std::vector<int> foo]
..."

the generated code for that rule will start with

"std::vector<int> foo = NULL;"

which will (obviously) not compile. I've modified the relevant .stg to 
prevent it generating initialisation code for return values (declaration 
only), and not encountered any issues in my grammars thus far.
