Hi.

This tiny test:

// !!! Begin unboxfail.d !!!
import std.boxer;
import std.stdio;

int main(char[][]args)
{
     Box b = box("Hello World");
     if (unboxable!(char[])(b)) {
         writefln(unbox!(char[])(b));    // !!! Fails !!!
         return 0;
     } else {
         return 1;
     }
}
!!! End unboxfail.d

Compiled with:
gdc unboxfail.d -o unboxfail

Gives this error message:
ld: Undefined symbols:
__init_11TypeInfo_Pv


I use gdc 0.15 installed from Anders F Björklund's package for Mac OS X. 
I run under Mac OS X 1.4.2.

Is there a special trick to unboxing arrays, or have I stumbled upon a bug?

Good.

Is there a work-around that can be used in the mean time (I need to box 
and unbox int, float, char[] and my own class Block and it's decendant 
ContainerBlock only).

I would assume you can write something like this:
<code>
class StringBox
{
	this( char str[] )
	{
	// .. do something to encapsulate str into this object
	}
}



Box x = ( new StringBox("HelloWorld") );
</code>
i.e. write a small class or struct that hides the string, and then box 
that class and unbox it.

woops, I meant:
#Box b = box( new StringBox("HelloWorld") );
