Effect |
| 1 | Size of this class has been increased from 128 bytes to 136 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.

[+] class PolyTree (1)
| Change |
Effect |
| 1 | Size of this class has been changed from 48 bytes to 56 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. |
