Here is an interesting reading:

BTW: Is the bellow afirmation also valid for fpc??

"we alluded to the fact that while the constructor of an object is executing, if any exception is raised the destructor will automatically be called, the object will be freed and the exception is allowed to continue on its merry way."

Feel free to take it... But it's x86 specific asm code...

That is correct for FPC as well. And since it got fixed FPC doesn't even execute AfterConstruction and BeforeDestruction anymore in case of an exception in the constructor.
