--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Probably cfun->function_start_locus is inconsistent for them (or not set, in
which case we use DECL_SOURCE_LOCATION).

Sounds like a C++ frontend issue to me:

static tree
cp_parser_init_declarator (cp_parser* parser,
                           cp_decl_specifier_seq *decl_specifiers,
                           vec<deferred_access_check, va_gc> *checks,
                           bool function_definition_allowed_p,
                           bool member_p,
                           int declares_class_or_enum,
                           bool* function_definition_p,
                           tree* maybe_range_for_decl)
{
...
          if (decl != error_mark_node && DECL_STRUCT_FUNCTION (decl))
            {
              /* This is where the prologue starts...  */
              DECL_STRUCT_FUNCTION (decl)->function_start_locus
                = func_brace_location;

but for templates we likely don't have DECL_STRUCT_FUNCTION allocated at this
point.
