Summary: ICE with deferred character length derived type
component
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: kargl@gcc.gnu.org
The following code gives an ICE. I haven't check it against
the standard yet to determine if this is valid or invalid
code. Nonetheless, it should not ICE.
module simple_module
implicit none
type :: item_type
character(len=:), allocatable :: key
end type item_type
end module simple_module
program test_simple
use simple_module
implicit none
type(item_type) :: item
! ICE
item = item_type('key')
! item%key = 'key'
end program

For a variant (original, longer version), see:
http://gcc.gnu.org/ml/fortran/2011-05/msg00129.html
(That program compiles and runs w/o valgrind errors with ifort 11.1)

See also: PR 45170.
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:
http://gcc.gnu.org/wiki/Fortran2003Status
http://gcc.gnu.org/onlinedocs/gfortran/Fortran-2003-status.html

--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-01-24 08:04:35 UTC ---
The ICE is fixed - but deferred-length character components are not supported:
Instead of an internal compiler error, one now gets a "not yet implemented"
error.
Its implementation of is now tracked at PR 51976.
