Temporary static arrays on stack get corrupted with dmd -m64

[H. S. Teoh]

Code (compile with dmd -m64):
	import std.stdio;
	struct S {
		short[4] x;
		this(short[4] args...) {
			x[] = args[];
		}
		bool opEquals(in S s) const {
			for (auto i=0; i < 4; i++) {
				if (this.x[i] != s.x[i])
					return false;
			}
			return true;
		}
	}
	void main() {
		assert(S(1,2,3,4) == S(1,2,3,4));
	}

Output: the assertion in main fails. Inserting writeln's indicate that
the parameter s to opEquals is corrupted (has garbage values). Trying to
writeln either argument causes a segfault.

Compiling with -m32 works no problem.

Is this a known issue?
