Okay, that worked nicely for that source.  Going back to the source I
started with, I hit a different abort, in llvm_unreachable_internal()
instead:

Should not see dependent types
UNREACHABLE executed at
/home/hotellnx94/peeterj/clang/sources/llvm/tools/clang/lib/AST/ASTContext.cpp:1322!

Program received signal SIGABRT, Aborted.

I'm having trouble producing a standalone sample for this internal error.
 I'm guessing this isn't expected or a known issue.
