Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 16 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 costructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

namespace v8
[+] class TryCatch (1)

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field isolate_ has been added at the middle position of this structural type.	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
