Bug #: 56650
Summary: Odd error messages with C_SIZEOF
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: burnus@gcc.gnu.org
As PR 56649, this is another issue which causes compilation problems with MPICH
(for its MPI 3 implementation).
Compiling the program below gives:
integer,parameter :: MPI_STATUS_SIZE = c_sizeof(MPI_Status_C_obj)
1
Error: Unclassifiable statement at (1)
Or for the variant:
= c_sizeof(MPI_Status_C_obj)*8/bit_size(0)
1
Error: Invalid character in name at (1)
module m
use iso_c_binding, only: c_sizeof, c_int
implicit none
integer(c_int), bind(C) :: MPI_Status_C_obj
integer,parameter :: MPI_STATUS_SIZE = c_sizeof(MPI_Status_C_obj)
! integer,parameter :: MPI_STATUS_SIZE2 &
! = c_sizeof(MPI_Status_C_obj)*8/bit_size(0)
end module m

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2013-03-18 09:22:34 UTC ---
Note that the code is VALID. "c_sizeof" is a specification inquiry:
"A specification inquiry is a reference to [...] (4) the function C_SIZEOF from
the intrinsic module ISO C BINDING (15.2.3.7), or [...]"
(F2008, "7.1.11 Specification expression")
And those are allowed in constant expressions:
"(4) a specification inquiry where each designator or function argument is
(a) a constant expression or
(b) a variable whose properties inquired about are not
(i) assumed,
(ii) deferred, or
(iii) defined by an expression that is not a constant expression,"
(F2008, "7.1.12 Constant expression")

Probably due to not simplifying c_sizeof(), cf. PR 36437. Related PR46641 and
PR45824
