Bug ID: 85001
Summary: [6/7/8 Regression] ICE in gfc_build_array_type, at
fortran/trans-types.c:1420
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
gfortran-8 changed between 20171105 and 20171112.
gfortran-7 changed between 20180111 and 20180125.
gfortran-6 changed between 20180110 and 20180207.
$ cat z1.f90
program p
type t
end type
call s
contains
real function f(x)
class(t) :: x
dimension :: x(:)
f = 1.0
end
subroutine s
type(t) :: x(2)
real :: z
z = f(x)
end
end
The error message was formerly a bit misleading :
$ gfortran-8-20171105 -c z1.f90
z1.f90:14:12:
z = f(x)
1
Error: Rank mismatch in argument 'x' at (1) (scalar and rank-1)
$ gfortran-8-20180318 -c z1.f90
z1.f90:6:0:
real function f(x)
internal compiler error: Segmentation fault
