Problems with Data Types, High Severity (2)

ANN.h
[+] class ANNpointSet (2)

	Change	Effect
1	Size of virtual table in this class has been changed from 32 bytes to 36 bytes.	The layout of virtual tables in its subclasses has been changed. Call of any virtual method in subclasses may result in crash or incorrect behavior of applications.
2	Pure virtual method ANNpointSet::annkFRSearch ( ANNpoint q, ANNdist sqRad, int k, ANNidxArray nn_idx, ANNdistArray dd, double eps ) has been added to this class.	1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method. 2) The layout of virtual table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
