Invalid calculation n value:
-        auto n = this.length / bitsPerSizeT;
+        auto n = (this.length + (bitsPerSizeT - 1)) / bitsPerSizeT;


Test:
//                  0 1 2 3 4 5 6 7|0 1 2 3 4 5 6 7|0 1 2 3 4 5 6 7|0 1 2 3 4 5
6 7
static bool[] bf =
[1,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];
static bool[] bg =

BitArray f; f.init(bf);
BitArray g; g.init(bg);
assert(f != g);
