(j3.2006) issues with branching out a BLOCK construct

I can't recall if this has been discussed. Consider the following code
BLOCK
real, allocatable :: x(:), y(:)[:]
...
allocate (x(n))
allocate (y(n)[*])
...
if (condition) GO TO 10
,..
END BLOCK
10 .. code to continue
...
The issue is when the execution branches out of the BLOCK construct, what
happens to local allocatable variables x and y. Are they automatically
deallocated? Does standard say anything about their deallocation? Also
what happens to the entities require finalizations? Does branching out of
a BLOCK construct considered as termination of a BLOCK construct?
