Bug #: 56800
Summary: [fortran-dev Regression] move_alloc_13.f90 failure
Classification: Unclassified
Product: gcc
Version: fortran-dev
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: tkoe...@gcc.gnu.org
The move_alloc_13 failure on the fortran-dev branch can be reduced
to a wrong setting of sm to zero in:
ig25@linux-fd1f:~/Krempel/Branch> cat mv.f90
type t
end type t
type, extends(t) :: t2
integer :: a
end type t2
class(t), allocatable :: y(:), z(:)
allocate(y(1), source=[t2(2)])
end
ig25@linux-fd1f:~/Krempel/Branch> gfortran -fdump-tree-original mv.f90
[...]
__builtin_memset (y._data.base_addr, 0, 4);
y._data.dtype = 41;
y._data.dim[0].lower_bound = 1;
y._data.dim[0].extent = 2 - y._data.dim[0].lower_bound;
y._data.dim[0].sm = 0;
y._data.offset = -1;
