    Reproducer(`test.f90`):
```f90
type t
    integer, allocatable :: a(:,:)
end type

type(t) :: str(1)
integer, allocatable :: b(:,:)

where((/.true./))str=(/(t(reshape((/b/), (/1,1/))), i=1,1)/)
end
```

The following is the result of `flang-new test.f90`:
```console

error: failure in HLFIR bufferization pass
error: Lowering to LLVM IR failed

```

The above failure is also reproducible on Godbolt:
