I'm trying to program some sorting algorithms in D (mainly to play
around). So I have a module called "sort" and a "main.d" which imports
"sort". I have a template Sorting, which has the different sorting
algorithms. 

Now, in the module, I wanted to print out an array, with

writefln("%s\n",elements);

where elements is "T[] elements" and T is the template parameter. Now,
when I compile everything:

 gdc -fbounds-check -c sort.d
 gdc -fbounds-check -o main sort.o main.d

/tmp/ccSBSZs8.o:(.data+0x20): undefined reference to
`_init_12TypeInfo_AAh' collect2: ld returned 1 exit status

I get this error. Can someone perhaps tell me where the problem is ? If I
remove the "writefln(...)" everything links right again.

Thank you.

Here is the code for sort.d:
------------------------
module sort;

import std.stdio;
import std.random;

template Sorting(T) {

        void insertSort(T[] elements)
        in{
        }
        out{
        }
        body {
                writefln("%s\n",elements);
        }
}
------------------------
and main.d
------------------------
import std.stdio;
import std.random;
import sort;

static uint ELNUM = 4000;

int main(){

        ubyte[][] strings = new ubyte[][ELNUM];

        for(int i = 0;i<ELNUM;i++){
                strings[i] = new ubyte[rand()%200];
                strings[i][] = (rand()%60)+'a';
        }

        Sorting!(ubyte[]).insertSort(strings.dup);

        return 0;
}
-------------------------
I tried to reduce it to a minimum that still works.

Quick fix: add this line to sort.d:

alias Sorting!(ubyte[]) Sorting_ubyte;

The alias name can be anything. It's an ugly fix, but it works.

Thanks. I fixed it by just writing a function that does it. Anyway, what I
wanted to know was more bug in compiler or my error.

I don't know about you but I tested it with GDC. Maybe someone who uses DMD can 
test it and see what happens (I have a gut feeling it's going to fail too), and 
if it's so, then a bug report can be posted to D.bugs.
