2) The memory layout in this class has been shifted by 8 bytes. |
|---|
| 2 | 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. |
|---|
| 3 | Pure virtual method exception::clone ( ) 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. |
