Short answer: No.

Longer answer: I think this needs to be the same kind of synchronisation as 
ALLOCATE, see which contains essentially identical wording (but for 

Therefore I think this should pass as is.

I think I would have to agree with this.  The intrinsic type case is clearly 
intended to work otherwise we would not have worded C4104 the way that we did.

I don't however think that this is a fatal flaw in this interp, though we should 
certainly fix it sometime.

So my vote is

Yes  No   Number     Title

-C-  ---  F08/0040   MOVE_ALLOC for coarrays
-Y-  ---  F08/0074   Implicit type in BLOCK construct
-Y-  ---  F08/0077   Function references as variables in DATA statements
-Y-  ---  F08/0078   Are the IEEE values +0 and -0 distinguished
-Y-  ---  F08/0079   NAMELIST and type specification
-C-  ---  F08/0080   Array constructors with polymorphic values
-Y-  ---  F08/0081   Deallocation error handling
-Y-  ---  F08/0082   Generic identifier and dtv arguments
