reduced boost test case

The attached code, reduced from libs/multi_index/test/test_key_extractors.cpp ,
compiles fine in g++ and asserts clang++ as follows:

clang: SemaTemplate.cpp:3066:

clang::Sema::BuildExpressionFromDeclTemplateArgument(const
clang::TemplateArgument&, clang::QualType, clang::SourceLocation): Assertion
`!RefExpr.isInvalid() && Context.hasSameType(((Expr*)
RefExpr.get())->getType(), ParamType)' failed.
