Hm, with the original schema the compiler crashes. I will take a closer
look at this and will let you know what I find.

Your XML document uses xsi:type while you compiled your schemas without
--generate-polymorphic. I am pretty sure this is the cause of your
problems. See Section 2.11, "Mapping for xsi:type and Substitution Groups"
in the C++/Tree Mapping User Manual for details:
