           Summary: [C++11][constexpr] Constructor Parenthesized
                    Initialization of Member Array Crash

Reproduce case

Crash when using a parenthesized initialization of a member array with a
constexpr constructor.

Whittled the reproduce case down as much as I could, all parts of the reproduce
case source seem relevant to causing the crash. Switching to the standard
initialization of the member array without parentheses fixes the crash.

Crash error:

main.cpp:46:46: internal compiler error: in verify_ctor_sanity, at
cp/constexpr.c:2635
     constexpr Foo<int, bool> foobar(32, false);
