strange bug with unions?

[seen via Digitalmars-d]

I don't know why but when using a template union with a static 
ubyte array i get bizarre results!

module main;

import std.stdio;
private union ByteConverter(T)
{
	ubyte[T.sizeof] bytes;
	T value;
}

ubyte[] toBytes(T)(T from) if (!is(T == const))
{
	ByteConverter!T converter;
	converter.value = from;
	return converter.bytes;
}

T fromBytes(T)(in ubyte[] bytes)
{
	ByteConverter!T converter;
	converter.bytes = bytes;
	return converter.value;
}

void main(string[] args)
{
	writeln(fromBytes!uint(toBytes(34u)));// should print 32 but 
prints 1244564
}

why dose it print 1244564 the array is static size so why is it 
acting like bytes is a pointer not a static array?
