Wrong memory size is allocated when binding vector in ocilib_impl.hpp. For example if binding 10 Raw rows with a length of up to 2000 bytes, only 10 bytes are allocated instead of 20 000 bytes.

template <class TObjectType, class TDataType>
inline void BindArray::BindArrayObject<TObjectType, TDataType>::AllocData()
{
    _data = new TDataType[_elemCount];

    memset(_data, 0, sizeof(TDataType) * _elemCount);
}

Must be

template <class TObjectType, class TDataType>
inline void BindArray::BindArrayObject<TObjectType, TDataType>::AllocData()
{
    _data = new TDataType[_elemCount * _elemSize];

    memset(_data, 0, sizeof(TDataType) * _elemCount * _elemSize);
}

Hi,

Thanks :)

The funny thing is that I was going to commit a fix at the same time i got your mail.

I've looked at the pull request. My fix is slightly different and address also the Raw size when fetched after insert.
In you sample code a Raw with size 650 once inserted and fetched later is returned with size 2000 which was the max size at insert time. I've fixed that as well.
See my latest commit.

Thanks again for reporting issues :)
