Confirmed that this also fails with gcc trunk (as of about 5AM UTC
today). The stack trace is the same. Is there something I need to do
to use the ctype<char16_t> you've added?
Actually I can't spot that template specialisation in the trunk code
(ie `grep -r 'ctype.*char16_t.*'` returns no matches, either in the
source or in $HOME/gcc-5.0/include). If you could have a look and see
if it's sitting in a workspace somewhere, I'd be grateful.
