This check is incorrect.
Via SetSize2(row, 5); SetSize2(row, 0);, line.size becomes 0, but that does not mean the backing memory should not be freed.

Though, the allocation/deallocation is considerably flawed. The memory pointed to by line.col must only be freed when it does not point into oneblock. Unfortunately, that is not easy to check, as there is no end pointer.

memcpy (p, line.col, line.maxsize * elsize);
delete [] (char*)line.col;
}

line.col = p;
line.maxsize += 5;
}

line.size++;
}
