Additionally a better/valid example :
$ cat z3.f90
program p
type t
character(:), allocatable :: c(:)
end type
type(t), allocatable :: x
x = t(['abc', 'uvw'])
associate (y => x%c(:)(:))
print *, y
end associate
end
# should print :

--- Comment #4 from José Rui Faustino de Sousa <jrfsousa at gcc dot gnu.org> ---
I am looking into this.
I think I already have a patch for the ICE, but there are further problems
which I am trying to solve.
Best regards,
José Rui

Fortran: Fix some of the bugs in associate [PR87477]
2023-04-08 Paul Thomas <pault@gcc.gnu.org>
gcc/fortran
PR fortran/87477
* iresolve.cc (gfc_resolve_adjustl, gfc_resolve_adjustr): if
string length is deferred use the string typespec for result.
* resolve.cc (resolve_assoc_var): Handle parentheses around the
target expression.
(resolve_block_construct): Remove unnecessary static decls.
* trans-array.cc (gfc_conv_expr_descriptor): Guard string len
expression in condition. Improve handling of string length and
span, especially for substrings of the descriptor.
(duplicate_allocatable): Make element type more explicit with
'eltype'.
* trans-decl.cc (gfc_get_symbol_decl): Emit a fatal error with
appropriate message instead of ICE if symbol type is unknown.
(gfc_generate_function_code): Set current locus to proc_sym
declared_at.
* trans-expr.cc (gfc_get_expr_charlen): Retain last charlen in
'previous' and use if end expression in substring reference is
null.
(gfc_conv_string_length): Use gfc_conv_expr_descriptor if
'expr_flat' is an array. Add post block to catch deallocation
of temporaries.
(gfc_conv_procedure_call): Assign the parmse string length to
the expression string length, if it is deferred.
(gfc_trans_alloc_subarray_assign): If this is a deferred string
length component, store the string length in the hidden comp.
Update the typespec length accordingly. Generate a new type
spec for the call to gfc_duplicate-allocatable in this case.
* trans-io.cc (gfc_trans_transfer): Scalarize transfer of
deferred character array components.
