Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

template <char first, char... data>
struct CTArray
{
static constexpr unsigned long count = sizeof... (data);
};
struct Str
{
template <typename T>
Str(T...) {}
};
template <typename T>
struct ToStr;
template <char... letters>
struct ToStr <CTArray <letters...>>
{
static Str
get ()
{
return { letters... };
}
};
using Foo = CTArray <'F', 'o', 'o'>;
Str str(ToStr <Foo>::get ());
ICEs with -std=c++11. Before r198750 it just errored out on the testcase (is
it invalid, right?), in r198800 ICEs, haven't bisected more.
