Test case

When building headers similar to the attached reduced test case, I get an
assertion failure inside clang:

[nwhitehorn at comporellon /usr/home/nwhitehorn]$ clang++ test.cpp 
Assertion failed: (ICS->UserDefined.After.ReferenceBinding &&
ICS->UserDefined.After.DirectBinding && "Expected a direct reference
binding!"), function CheckReferenceInit, file
