Problems with Data Types, High Severity (7)

	Change	Effect
1	Size of this class has been changed from 32 bytes to 40 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 84 bytes to 92 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 120 bytes to 124 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been increased from 204 bytes to 228 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been changed from 28 bytes to 32 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Pure virtual method AbstractMessagingPort::remotePort ( ) 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.
