More fallout from the variadic templates on mainline:
===========================================================
template<typename... T> int foo(const T&)
{
union { T t; };
return t;
}
void bar()
{
foo(0);
}
===========================================================
bug.cc:1: error: parameter packs not expanded with `...':
bug.cc:1: note: 'T'
bug.cc: In function 'int foo(const T&) [with T = <expression error>]':
bug.cc:9: instantiated from here
bug.cc:4: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_conversions,
at cp/search.c:2432
Please submit a full bug report, [etc.]
Similar to PR31434 and PR31435 as this is also invalid use of a
parameter pack in a function argument.
