Yes, but I don't knwo if this is really a bug. It happens only with an
empty scope. My case was:
statement
scope {
}
: ^(PREFIX PNAME URIREF) { ParserUtils.SetPrefix($PNAME.Text, $URIREF.Text); }
| ^(BASE URIREF) { ParserUtils.SetBase($URIREF.Text); }
| ^(STATEMENTS subject
(predicateObjectList[$subject.node] { Statements.AddRange($predicateObjectList.stms); })+ )
;
I know an empty scope probably should not be used (I was debugging and I
just left it there to avoid too much retyping) but I suppose it should
generate right code or fail the code generation not fail during the
compile step.
