    Description

      QGeoCoordinate triggers a BC break inside QMetaType when running a 5.4 built application against 5.5. If it is built against Qt 5.4.1 and then ran against Qt 5.5.0 beta then the message:

      QMetaType::registerType: Binary compatibility break. 
Type flags for type 'QGeoCoordinate' [1386] don't match. Previously registered TypeFlags(0x307), now registering TypeFlags(0x107). This is an ODR break, which means that your application depends on a C++ undefined behavior.

      appears.
