[Bug fortran/51550] ICE in gfc_get_derived_type, at fortran/trans-types.c:2401


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51550

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2011-12-14 10:26:05 UTC ---
I think it is a duplicate of pr47545, pr48654, pr49050, pr51075, and pr51393
(note that only pr48654 is marked as a duplicate of pr47545; if there is an
agreement about it, I can mark the other PRs as duplicate). From
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49050#c2 :

It is known that deferred character length components do not work - they have
not been implemented. I think we really should add a gfc_error("Sorry not
implemented") as it is not the first such bug has been reported.

By the way, the documentation states this - albeit a bit hidden:

http://gcc.gnu.org/gcc-4.6/changes.html#fortran
http://gcc.gnu.org/wiki/GFortran#GCC4.6
 "Deferred type parameter: For scalar allocatable and pointer variables
  the character length can be deferred."
 (In particular: For components and for arrays, the length cannot be deferred.)

And a bit more explicitly:
