• Charles Hixson via Digitalmars-d-learn (14/14) Mar 15 2015 What is: Orphan format arguments: args[0..1]
• anonymous (7/10) Mar 15 2015 It means you gave `format` more arguments than placeholders.

It appears to come from within unittest at the line:
string    s    =    "{0}".format(cast(int)d2[i]);

d2 is:
     ubyte    d2[];
It should be 512 bytes long, but that hasn't been checked at the point 
of the error.
The compilation used was:
rdmd --main -unittest -Dddocs  blockf.d
(but dmd gave the same error on a slightly mover complex version)

The compiler was:
DMD64 D Compiler v2.066.1

`format` uses C style % placeholders, not the brace syntax like 


So make that:
string    s    =    "%s".format(cast(int)d2[i]);

By the way, I don't see a need for the cast.
