Reduced testcase:
template typename
struct A;
template typename T
struct A T
{
typedef T type;
};
template typename T
constexpr T foo (typename A T::type __t) noexcept
{
return static_cast T (__t);
}
template class T1, class T2
struct B
{
T1 t1;
T2 t2;
template class U
constexpr B (U __x, const T2 __y) : t1 (foo U (__x)), t2 (__y) {}
};
static inline constexpr bool
fn1 (const char c)
{
return ('0' = c) (c = '9');
}
static inline constexpr bool
fn2 (const char c)
{
return (('A' = c) (c = 'Z')) || (('a' = c) (c = 'z'));
}
static constexpr bool
fn3 (const char *const x)
{
return (x[1] == '\0' x[0] == ']') ? true : (!fn1 (x[0])) ? false : fn3
(x[1]);
}
static constexpr bool
fn4 (const char *const x)
{
return (x[0] == '\0') ? fn3 (x[1]) : fn4 (x[1]);
}
static inline constexpr bool
fn5 (const char *const x)
{
return fn2 (x[0]) ? fn4 (x) : false;
}
struct C final
{
constexpr C (const char *const t1) : c (fn5 (t1) ? 199 : 69) {}
unsigned c;
};
B C, C p (a, b);
Started to ICE in between r175000 and r175062.
