Problems with Data Types, High Severity (4)

	Change	Effect
1	Size of this class has been changed from 64 bytes to 72 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 408 bytes to 480 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 64 bytes to 72 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 neighboring 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 200 bytes to 184 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.

Problems with Symbols, Low Severity (2)

	Change	Effect
1	The initial value of this global data has been changed from $Id: Constants.hpp 6817 2010-02-08 14:42:35Z karney $ to $Id: Constants.hpp 6827 2010-05-20 19:56:18Z karney $.	Applications will use an old value of this data instead of the new one. This may cause incorrect behavior of applications.

	Change	Effect
1	1st parameter degree has been renamed to angle.	Renaming of a parameter may indicate a change in its semantic meaning.
