* resolve.c (resolve_assoc_var): If the target expression is a
deferred charlen dummy and the associate name shares the
charlen, generate a new one. Make sure that new charlens are in
the namespace list so that they get cleaned up.
* trans-array.c (gfc_is_reallocatable_lhs): Associate names are
not reallocatable.
* trans-decl.c (gfc_get_symbol_decl): Put deferred character
length dummy and result arrays on the deferred initialization
list so that the variable length arrays can be correctly dealt
with.
* trans-expr.c (gfc_conv_string_length): Return if 'expr' is
NULL rather than ICEing..
