I tried NAG, PGI and xlf.  All of them accept the 'nested' version,
but only PGI accepts the original code.

xlf 14:

"pr64678.f90", line 10.22: 1514-091 (S) Invalid structure component reference. 
The object name and all component names (except the rightmost) must be of type
derived.

NAG 6:

NAG Fortran Compiler Release 6.0(Hibiya) Build 1032
Product NPL6A60NA for x86-64 Linux
Copyright 1990-2014 The Numerical Algorithms Group Ltd., Oxford, U.K.
f95comp version is Hibiya(6.0) Build 1032
Error: pr64678.f90, line 10: A is not of derived type
       detected at %@MAP

So I think Steve has pointed into the right direction.
Nevertheless, consider posting your code on c.l.f.
