Bug #: 53544
Summary: Derived-type components in namelist group declaration
produces error
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: townsend@astro.wisc.edu
Created attachment 27533
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27533
Example program illustrating namelist problem
In the attached example program, the use of derived-type components in the
namelist group declaration causes the following errors:
foo.f90:12.19:
namelist /bar/ ct%a, ct%b
1
Error: Syntax error in NAMELIST statement at (1)
foo.f90:14.17:
read(*, NML=bar)
1
Error: Symbol 'bar' at (1) must be a NAMELIST group name
It is my understanding that the variables in a namelist group declaration must
not be a dummy array with non-constant bound, a variable with non-constant
character length, an automatic object, an allocatable array, a pointer, or have
a component at any depth that is a pointer or is inaccessible. The case in the
example program falls into none of these categories, and therefore should be
accepted by the compiler as valid code.

Why don't you simply write
namelist /bar/ ct
?
Anyway, neither the NAG nor the Intel compiler accept your program:

>From the F2008 draft standard:
R564 namelist-group-object is variable-name
R603 variable-name is name
C603 (R603) variable-name shall be the name of a variable.
I think that ct%a is a structure component and does not
qualify as the name of a variable.

Right. Also our error message is not worse than that of other compilers, so I
think this can be closed as INVALID.
