Harvind found a bug in BitVector.cpp:
Basically the unpack method and fillField method assume MSB-first bit packing. The unpack method calls fillField for each byte that needs to be unpacked. The problem occurs on its final call to fillField when it has a partial byte to unpack; it uses the LSB bits instead of the MSB bits.
