Subject: [Bug fortran/64229] New: internal compiler error when assigning allocatable arrays of character(:)
Date: Mon, 08 Dec 2014 19:12:00 -0000 [thread overview]
Message-ID: <bug-64229-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64229
Bug ID: 64229
Summary: internal compiler error when assigning allocatable
arrays of character(:)
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: ondrej.certik at gmail dot com
Created attachment 34223
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34223&action=edit
Test program to trigger ICE
The following code (also attached):
$ cat test_ice.f90
program test_ice
character(:), allocatable :: x(:), y(:)
x = y
end
Produces an ICE:
$ gfortran -v test_ice.f90
Driving: gfortran -v test_ice.f90 -l gfortran -l m -shared-libgcc
Using built-in specs.

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
This seems to be caused by the same bug as in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62142, because this compiles:
$ gfortran -fno-realloc-lhs test_ice.f90
$
and gfortran 4.7.2 also compiles:
$ gfortran test_ice.f90
$
So probably the fix in #62142 didn't fix all the cases.
The above test case is the minimal example that still triggers the compiler
error. The actual code where I discovered this problem is:
type, extends(parameter_entry), public :: any_matrix
private
class(*), allocatable :: value(:,:)
...
end
subroutine get_matrix_character (this, value, errc)
class(any_matrix), intent(in) :: this
character(:), allocatable, intent(out) :: value(:,:)
logical, intent(out) :: errc
select type (v => this%value)
type is (character(*))
value = v
errc = .false.
class default
errc = .true.
end select
end subroutine
It works with PGI and Intel.
