Deferred length-type parameters for character in derived types are not 
yet implemented.

That's tracked in PR 45170, but not well documented*:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45170#c9
(* currently, it seems to be only mentioned at http://gcc.gnu.org/wiki/OOP )

As the 4.6 release is imminent**, it is extremely unlikely to be fixed 
for the 4.6 release, though someone might convert the ICE into a nicer 
error message. One might mention it in the release notes***, though.
