Consider the following code
```
real, allocatable :: r1(:)
call sub(r1, [real :: ], 0)
contains
subroutine sub(obj, source, size)
real, allocatable :: obj(:)
real :: source(size)
integer :: size
allocate(obj, source=source)
print*, allocated(r1)
end subroutine
end
```
Flang failed at runtime with
```
> a.out
fatal Fortran runtime error(t.f:2): Assign: left-hand side variable is neither allocated nor allocatable
IOT/Abort trap(coredump)
```
Flang supports allocating zero-sized array as shown in issue #148255, this variation should also be supported.
