v8.h
namespace v8
[+] class HeapStatistics (1)
| Change |
Effect |
| 1 | Size of this class has been increased from 16 bytes to 20 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. |
