Wrong satellite position computation from broadcast ephemeris for Beidou GEO satellites. This issue occurs only in case of GEO satellites. For IGSO and MEO satellites everything is OK. Please see picture as proof:

The cause of the problem is that svXvt method in OrbitEphdoesn't marked as virtual. So, when you use BDSEphemerisobject through pointer to OrbitEph ( as in Rinex3EphemerisStore::getXvt), you really call svXvtfrom OrbitEph, instead of method, redefined in BDSEphemeris.
