--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The code has undefined behaviour, you are not allowed to add declarations to
namespace std, especially not std::initializer_list which is very closely tied
to the compiler.
On trunk we get the following stack trace:
il.cc: In function ‘int test()’:
il.cc:16:23: error: converting to ‘X’ from initializer list would use explicit
constructor ‘X::X(std::initializer_list<int>)’
X x = {10, 10, 10};
