This bug has been resolved. Update graimp.cpp from CVS to solve it.

The problem was that Evaluate method trust always in castingFunction_ call, but this function
could returns with a null BSyntaxObject.

In BGrammar::Evaluate(List*) method, when a returned result (BSyntaxObject*) has different
type than (this) object (BGrammar), a castingFunction_ is called, but its output could have no
value. To control that, Evaluate method needs an else branch, returning null value.

(We need to improve Error Information, maybe a static object could collect all attributes
related with an error before show the message)
