Bug 20475 – Struct of static array of strings is bitwise-compared instead of member-wise

Code: ------ struct S { string[2] x; } void main() { auto s = S(["a", "b"]); auto t = S(["a", ""]); t.x[1] ~= "b"; assert(s == t); } ------ Expected result: assertion should pass. Actual result: assertion fails. Looking at the disassembly, it appears that the struct comparison with == is implemented as a bitwise comparison, which is wrong because 'string' is not a POD and therefore the static array member ought to be compared member-wise rather that bitwise.
