If pending_length is not zero the datatype engine believe that a partial conversion is still in the buffer attached to the convertor. We have to force it to zero for all new convertors. This bug is still half fixed until I figure out a correct way to do it when we clone a convertor ... Anyway, this future correction will not affect open mpi.
