Problems with Data Types, High Severity (2)

platformdependent.h
namespace Attica
[+] class PlatformDependent (1)

	Change	Effect
1	Pure virtual method PlatformDependent::hasCredentials ( QUrl const& ) const 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 v-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.

[+] class Provider (5)

	Change	Effect
1	Size of this type has been changed from 12 bytes to 4 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Virtual method Provider::metaObject ( ) const has been overridden by QObject::metaObject ( ) const.	Method QObject::metaObject ( ) const will be called instead of Provider::metaObject ( ) const by old applications.
3	Virtual method Provider::qt_metacall ( enum QMetaObject::Call, int, void ) has been overridden by QObject::qt_metacall ( enum QMetaObject::Call, int, void ).	Method QObject::qt_metacall ( enum QMetaObject::Call, int, void ) will be called instead of Provider::qt_metacall ( enum QMetaObject::Call, int, void ) by old applications.
4	Virtual method Provider::qt_metacast ( char const* ) has been overridden by QObject::qt_metacast ( char const* ).	Method QObject::qt_metacast ( char const* ) will be called instead of Provider::qt_metacast ( char const* ) by old applications.
5	Virtual method Provider::~Provider ( ) has been overridden by QObject::~QObject ( ).	Method QObject::~QObject ( ) will be called instead of Provider::~Provider ( ) by old applications.
