! { dg-do run }
! Tests the fix for PR34820, in which the nullification of the
! automatic array iregion occurred in the caller, rather than the
! callee. Since 'nproc' was not available, an ICE ensued. During
! the bug fix, it was found that the scalar to array assignment
! of derived types with allocatable components did not work and
! the fix of this is tested too.
