#62: Bug in factorSparseSmall (CoinFactorization2.cpp)

Comment(by forrest):

 CoinFactorization is pretty solid so it may be a problem with fastdual.
 What are the values of j, space, put, lengthU_ and numberInPivotColumn?
 If they are boring then this is going to be very difficult to debug
 without code.  If we are lucky it could be a rare boundary case and
 getColumnSpace is returning true when it should be false due to some code
 being out by one.

 Rather than just give me lengthU_ can you print *this to get more
 printout?
