deeply into problems with minor languages.

Is it possible to get a backtrace on the particular crash?  The compiler
frontend is aborting because the 'type' parameter in the IntegerExp
constructor is a null pointer.   However, that does not make sense as all
basic types and aliases should have been allocated before compilation began.
