SMAKE fatal error: command "dmd" returned with error code 1


I am guessing 'Aaik' is a type signature, but I cannot decode it...

I would like to hunt this down, but I honestly don't know where to look.

Any help is appreciated.

1) Cut the code down until any further reductions removes the error message.

2) Try a search for "aik" in the source code.

3) Enable debug info and compile(without linking), search for "aik" in the
object file.

4) Try to write a dummy "std/typeinfo/ti_*" class.

Thanks Thomas.

This is pretty strange.  Its difficult to debug this because it is in a 
stack template class I wrote(attached).  Believe it or not it is the 
writefln statement in the following routine:

   // Note: negative indices are from the end of the stack
   // ( this[-1] = last, this[0]=first )
   T   opIndex( int n )
   in { assert( mCount>0 ); }
   body
   {
     alias std.string.toString str ;

     if ( n<0 ) n = mCount + n;
     if( (n<0) || (n>=this.mCount))
     {
       char[] msg = "Attempting to index item %s %s items" ~ str(n) ~
         " with " ~ str( mCount ) ~ " items." ;
       writefln("Attempting to index item %s with %s items", n, mCount );
       throw new Exception("Stack Underflow: " ~ msg );
     }
     else  return data[n];
   }

If I comment out the writefln statement, everything links fine.
It even happens when i qualify using std.stdio.writefln.

Its a bit strange because (unless I am mistaken) the A in Aaik is a 
class reference type and I am passing no class references...

I can't reproduce it either (dmd & gdc Linux).

PS:
If it's a compiler bug, I am sure you can reduce this test case's size further.
