Bug ID: 101085
Summary: ICE in gfc_conv_intrinsic_to_class, at
fortran/trans-expr.c:1039
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gscfq@t-online.de
Target Milestone: ---
This invalid code z1 (rank mismatch scalar versus array) affects
versions down to r7. Case z2 is a correct variant of z1, similar
invalid case z3 is detected (integer instead of character) :
$ cat z1.f90
program p
type t
integer :: n
end type
class(t), allocatable :: c(:)
character(3) :: a = 'abc'
c = [t(1)]
if ( f(c, a) /= 1 ) stop 1
contains
integer function f(x, y)
class(t) :: x(:)
class(*) :: y(size(x))
f = size(y)
end
end
$ gfortran-12-20210613 -c z1.f90
z1.f90:8:8:
8 | if ( f(c, a) /= 1 ) stop 1
| 1
