I just happened to discover it, so I do not know much about it yet. It may have
to do with -std=c++17 on g++ 8.2.0, and I have a class semantic_type.
A workaround is to make the typedef'ed name qualified:
typedef <namespace>::semantic_type semantic_type;
So if I change to
%define api.value.type {<namespace>::semantic_type}
then it passes.
