Preprocessed source
Clang correctly diagnoses that 'enum E' is disallowed in the template
declaration, however, it segfaults afterwards. If std::underlying_type<E> is
removed, the segfault does not occur. Other templates such as std::vector<E> or
std::is_enum<E> do not trigger the error, nor does the mention of a
non-existent type (e.g. Bar<E>).
Platform is Linux x86_64 with Clang 3.4.1 and libstdc++ 3.3.6.</pre>
