(j3.2006) Question about deferred length type parameters

[Van Snyder]

If a pointer has deferred length type parameters, what becomes of them
when the pointer association status becomes disassociated (16.5.2.4) or
undefined (16.5.2.5)?  Do they remain defined (assuming they were
defined), or do they become undefined?

6.4.5 and 13.7.94 say you can't inquire them, but are there other cases?
One case I can imagine is that one establishes their values using
pointer assignment or allocation, deallocates the pointer, then
establishes an association status for it using C_F_POINTER.  Do the
deferred length parameters of FPTR thereby have defined values?

Do we need to specify in 4.2p8 that the initial values of deferred
length type parameters of a pointer are undefined, unless the pointer is
initially associated?  6.4.5 and 13.7.94 say you can't inquire them if
the pointer is not associated, but what if it became associated using
C_F_POINTER, which cannot assign values to deferred length parameters?
