Bug ID: 58351
Summary: ICE using c_f_pointer subroutine and derived types
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: h.lars...@fz-juelich.de
I got an segmentation fault using the c_f_pointer-subroutine and derived types:
program blah
use,intrinsic:: ISO_C_BINDING
type t_m
real,dimension(:),pointer::m
end type t_m
type foo
type(t_m)::i
end type foo
real,dimension(:,:),pointer::e
type(foo),target::b
call C_F_POINTER(C_LOC(b%i%m), e ,[1,1])
end program blah
It works fine and correct with ifort 13.1.0.
% gfortan -Wall -Wextra ice.f90
ice.f90: In function ‘blah’:
ice.f90:11:0: internal compiler error: Segmentation fault
call C_F_POINTER(C_LOC(b%i%m), e ,[1,1])
^
Please submit a full bug report,
% gcc -v
Using built-in specs.
