C++ memmove:

memmove(bounds + upperIndex + 2, bounds + upperIndex, (edgeCount - upperIndex) * sizeof(b2Bound));

D memmove:

memmove(bounds.ptr + upperIndex + 2, bounds.ptr + upperIndex, (edgeCount - upperIndex) * b2Bound.sizeof);

Is this a correct translation to D? Thanks.

Oh, and bounds in the C++ version is a pointer, while in the D version is an array.

Looks ok, unless b2Bound is a class.  Then the sizeof would be giving you the size of just the reference to the class.
