Problems with Data Types, High Severity (10)

	Change	Effect
1	Size of this class has been changed from 40 bytes to 48 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 40 bytes to 48 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 4 bytes to 12 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 44 bytes to 52 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 80 bytes to 88 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 increased from 64 bytes to 84 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 increased from 84 bytes to 100 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	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN16TiXmlDeclaration5ParseEPKc to _ZN16TiXmlDeclaration5ParseEPKcPK16TiXmlParsingData. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN13TiXmlDocument5ParseEPKc to _ZN13TiXmlDocument5ParseEPKcPK16TiXmlParsingData. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TiXmlElement5ParseEPKc to _ZN12TiXmlElement5ParseEPKcPK16TiXmlParsingData. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TiXmlElement9ReadValueEPKc to _ZN12TiXmlElement9ReadValueEPKcPK16TiXmlParsingData. This may cause "undefined reference" linker error in old client applications.

	Change	Effect

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Pure virtual method TiXmlBase::Parse ( char const* p, TiXmlParsingData const* data ) has been added to this class instead of TiXmlBase::Parse ( char const* p ).	Applications will provide an older method to the library instead of expected newely added virtual method. This may result in crash or incorrect behavior of applications.
