This produces:

   Error: Assert Failure example(4)

When I think it should produce

   1

 From the docs: (http://www.digitalmars.com/d/phobos/std_string.html)

------
char[] toString(long value, uint radix);
char[] toString(ulong value, uint radix);
     Convert value to string in radix radix.

     radix must be a value from 2 to 36. [...]
------

So you're just calling it with an invalid parameter value.

Hint: 1 wouldn't be a valid digit in base 1, just like 2 isn't one in 
base 2, A isn't one in base 10, etc.
So the only valid digit would be 0, and since extra leading zeroes are 
ignored, the only value that can possibly be represented in base 1 is 0 
itself.

I only want to comment that the missing return statement can also be the
source of the assertion. Either

void main(){
...
}

or


int main( char[][] args ){
...
return 0;
}
