I have a question about Bisons GLR parser.
Is there a way for Bison (in %glr-parser mode) to return a parse tree (doesn't matter which) when parsing according to an ambiguous grammar?
Bison never returns a parse tree. If you want that, you need to define its construction in the actions. When people ask that question, they often need much less; if you so want, you may precise your programming situation.
