Further reduced:

void main()

     lockstep(iota(0, 10), [ 1 ]);
}

Strangely, the error message points at two comment lines in my 
installation of 2.063:

/usr/include/dmd/phobos/std/range.d(4716): Error: delegate dg (ref int, 
ref int) is not callable using argument types (int, int)
/usr/include/dmd/phobos/std/range.d(4717): Error: delegate dg (ulong, 
ref int, ref int) is not callable using argument types (ulong, int, int)

Lines 4716 and 4717 are the two lines of the following comment:

// For generic programming, make sure Lockstep!(Range) is well defined for a
// single range.
template Lockstep(Range)
{
     alias Range Lockstep;
}
