int
bar ()
{
return 42;
}
template <typename... R>
void foo (R... r, decltype (bar (r...)) x = 0) {}
int
main ()
{
foo (3);
}
ICEs starting with r140120.
Note, clang emits there a mangled name that c++filt can't demangle:
_Z3fooIJEEvDpT_DTcl3barspfL0p_EE
which llvm-cxxfilt demangles as void foo<>(decltype(bar(fp...)))
