cat > bug.d << CODE
// any combination of integral/floating point fields
// that sums up to an eightbyte triggers the bug.
template test(T...)
{
    struct Point
    {
        T fields;
    }

    enum N = 2; // N>=2 triggers the bug
    extern Point[N] bar();

    void foo()

        Point[N] _ = bar();
    }

This is most likely related to the recent ABI64 changes.

It's a x86-64 only bug.
I can reproduce it with the given code on linux, FreeBSD and OSX.

My recent work on the 64 bit calling convention seems to have fixed this.
