--- Comment #1 from TC <rs2740 at gmail dot com> ---
http://stackoverflow.com/questions/24378882/weird-gcc-array-initialization-behavior
appears to be related.

Minimal example:

struct A { A() { } };
int main() { A a[10] = A(); }

Compiles with GCC 4.6, 4.7, 4.8 and 4.9, in both C++98 and C++11 modes, even
though it shouldn't. However,

struct A { };
int main() { A a[10] = A(); }

does not compile in any of the GCC versions tested.

struct A { A() = default; };
int main() { A a[10] = A(); }

Compiles with GCC 4.9 in C++11 mode; does not compile with 4.6-4.8 in C++ 11
mode, however.
