Bug ID: 67817
Summary: Missing compilation error for some wrong conversions
in data
Product: gcc
Version: 5.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fortran@t-online.de
Target Milestone: ---
For the following cases an error message should be given.
Rejection makes it comparable to other ways of initialization.
(add-on to PR67804)
$ cat z1.f90
program p
type t
real :: a
end type
type(t) :: x6, x8
data x6 /t(.true.)/
data x8 /t('1')/
print *, x6
print *, x8
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z1.f90
$ a.out
1.40129846E-45
6.86636248E-44

Here, relevant errors are detected :
$ cat z2.f90
program p
real :: x6, x8
data x6 /.true./
data x8 /'1'/
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z2.f90
z2.f90:4:7:
data x8 /'1'/
1
Error: Incompatible types in DATA statement at (1); attempted conversion of
CHARACTER(1) to REAL(4)
z2.f90:3:7:
data x6 /.true./
1
Error: Incompatible types in DATA statement at (1); attempted conversion of
LOGICAL(4) to REAL(4)
---
$ cat z3.f90
program p
type t
real :: a
end type
type(t), parameter :: x6 = t(.true.)
type(t), parameter :: x8 = t('1')
end
$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z3.f90
z3.f90:5:32:
type(t), parameter :: x6 = t(.true.)
1
Error: Can't convert LOGICAL(4) to REAL(4) at (1)
z3.f90:6:32:
type(t), parameter :: x8 = t('1')

Error: Can't convert CHARACTER(1) to REAL(4) at (1)

--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
More examples analogous to z1.f90 :
$ cat z4.f90
program p
type t
complex :: a
end type
type(t) :: x6, x8
data x6 /t(.true.)/
data x8 /t('1')/
end
$ cat z5.f90
program p
type t
integer :: a
end type
type(t) :: x6, x8
data x6 /t(.true.)/
data x8 /t('1')/
end
$ cat z6.f90
program p
type t
logical :: a
end type
type(t) :: x1, x2, x3, x4, x8
data x1 /t(1)/
data x2 /t(1.)/
data x3 /t(1d0)/
data x4 /t((0.,1.))/
data x8 /t('1')/
print *, x1
print *, x2
print *, x3
print *, x4
print *, x8
end
