I'll second this :-)


Reading more on these intrinsics, now it appears a lot issues will be 
exposed.  In particular many of these intrinsics can appear in "constant 
expressions" that are supposed to be evaluated at compile time.  If an 
unallocated allocatables or disassociated pointers can be used in these 
expressions, although silly, then compilers have to do extra extra work to 
ignore them since they're all going be unallocated or disassociated. 
Indeed an annoying feature.

Cheers,
