    expr-parser.y: free allocated strings when parsing
    
    These are not handled automatically for us, and most TmplExpr node creation
    take `const char *` strings and therefore are not freeing these for us.
    
    An oversight I wish we could fix for parsing performance, but what can you
    do at this point.
