Ok, after the ICEs are fixed, let's come to runtime behavior. Here is a test
case:
implicit none
type test_type
integer :: i
end type
class(test_type), allocatable :: c
type(test_type) :: t
allocate(c)
c%i=3
t = transfer(c, t)
print *,t
end
With ifort and sunf95 this gives the expected output of "3", while gfortran
just spits out random numbers. -fdump-tree-original shows the following:
{
struct test_type transfer.0;
integer(kind=8) D.1884;
integer(kind=8) D.1883;
integer(kind=8) D.1882;
D.1882 = 16;
D.1883 = 4;
__builtin_memcpy ((void *) &transfer.0, (void *) &c, MAX_EXPR <MIN_EXPR
<D.1883, D.1882>, 0>);
t = transfer.0;
}
Clearly, the "&c" here should be "&c._data".
