This program:

import std.stdio;

void a(void[][] data...)
{
    writeln(data);
    b(data);
}

void b(void[][] data...)
{
    writeln(data);
    c(data);
}

void c(void[][] data...)
{
    writeln(data);
}

void main()
{
    a([]);
    a([]);
}

Prints:

[[]]
[[0, 0, 0, 0, 0, 0, 0, 0]]
[[8, 0, 0, 0, 88, 254, 19, 0]]
[[]]
[[0, 0, 0, 0, 0, 0, 0, 0]]
[[8, 0, 0, 0, 104, 254, 19, 0]]

Please note the difference between two a() calls. Also, data written from
within c() looks like array layout - 8 byte length and a pointer.

Tested with 2.059head and 32-bit Windows XP.
