 At least in one case (gcc 7.2) thorn Vectors seems to fail with a message
 that overloading is not allowed in line 671 of vectors.h
 {{{
  explicit constexpr vectype(scalar_t const &a) : v(props::set1(a)) {}
 }}}
 if vectorization is disabled (VECTORISE=no). My guess would be that in
 this case scalar_t and vector_t are the same and a conflict exists (or
 some other assumption is violated).

 I'll provide more details once I have a a nicer testcase.
