using GNU Fortran 95 (GCC) 4.1.0 20051126 (prerelease) with '-g -pedantic
-std=f95', I get a bad / no diagnostic for the following invalid code:
module M
integer, parameter :: A(2,2)=0
integer, parameter, dimension(2,2) :: B = CSHIFT(A,1)
end module M
END

------- Comment #1 from fxcoudert at gcc dot gnu dot org 2005-11-26 19:06 -------
The ice here is the same as the one in PR25049, but we shouldn't even come into
that part of the front-end. gfortran should recognize that CSHIFT is not
allowed here.
