struct S { int* data; @safe pure nothrow @nogc: this(ref return scope inout typeof(this)) inout{ pragma(inline, false); } } S[3] foo(ref S[3] r) { return r; } /// just copies memory and don't call S.__ctor example.S[3] example.foo(ref example.S[3]): mov rax, rdi mov rcx, qword ptr [rsi + 16] mov qword ptr [rdi + 16], rcx vmovups xmm0, xmmword ptr [rsi] vmovups xmmword ptr [rdi], xmm0 ret please make fix work with -betterC Thanks
