It looks to me like a singned-unsigned fault and in fact it is so. reducing the constant to a value 0x0000 till 0x7FFF will compile without error. The problem appears also only when: - the value is at the stack (local) - the second value in struct is used (u_16_value_0 works fine). GCC v 4.3.3 also works fine on the same code.
