Sounds like a compiler bug.
GeometryComponentFilter::filter_ro is a virtual function.
LinearComponentExtracter is the actual implementation for
this case (see last step in trace).
You would _always_ receive a SIGABRT if
GeometryComponentFilter::filter_ro is entered rather than
Indeed GeometryComponentFilter::filter_ro and ::filter_rw could
be made pure abstract methods.
