The following program gives a compile time error for a DATA assignment of
NULL() to a structure component. Probably related to 38917
Dick Hendrickson
SUBROUTINE PF0009
! fails on Windows XP
! gcc version 4.4.0 20081219 (experimental) [trunk revision 142842] (GCC)
TYPE :: HAS_POINTER
INTEGER, POINTER :: PTR_S
END TYPE HAS_POINTER
TYPE (HAS_POINTER) :: PTR_ARRAY(5)
DATA PTR_ARRAY(1)%PTR_S /NULL()/
end subroutine pf0009
C:\gfortran>gfortran try_pf0009.f
try_pf0009.f:11.38:
DATA PTR_ARRAY(1)%PTR_S /NULL()/
1
Error: NULL appears on right-hand side in assignment at (1)

------- Comment #1 from burnus at gcc dot gnu dot org 2009-01-20 07:26 -------
Confirm. Thanks for the report.
R532 data-stmt-constant is ...
or null-init
R507 null-init is function-reference
C506 (R507) The function-reference shall be a reference to the NULL intrinsic
function with no arguments
Probably a duplicate of PR 38917.

This has a trivial fix:
expr.c: 2913 becomes
if (have_pointer && lvalue->symtree->n.sym->attr.data)
Sorry about the lack of a diff - I will remedy this on submission:-)

Fixed on trunk. I am prepared to backport but the mood appears to be against
it.
Thanks for the report.
