Summary: ICE in gfc_conv_expr_descriptor, at
fortran/trans-array.c:7324
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
An invalid argument affects versions down to at least r5 :
$ cat z1.f90
program p
type t
end type
contains
integer function f(x)
class(t), allocatable :: x(:)
f = size(x(1))
end
end
$ cat z2.f90
program p
type t
end type
contains
integer function f(x)
class(t) :: x(:)
f = size(x(1))
end
end
