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?
