Created attachment 10565 [details] self contained (but probably not minimal) source that triggers ICE
Reduced testcase: FUNCTION reallocate_hnv(p,n,LEN) CHARACTER(LEN=LEN), DIMENSION(:), POINTER :: reallocate_hnv ALLOCATE(reallocate_hnv(n),stat=ierr) END FUNCTION reallocate_hnv
Confirmed, not a regression.
A little further reduced: FUNCTION reallocate_hnv(p,n,LEN) CHARACTER(LEN=LEN), POINTER :: reallocate_hnv ALLOCATE(reallocate_hnv) END FUNCTION reallocate_hnv
(In reply to comment #4) > A little further reduced: Actually that is a different bug. Anyways the reduced testcase looks like: FUNCTION reallocate_hnv(p,n,LEN) CHARACTER(LEN=LEN), DIMENSION(:), POINTER :: reallocate_hnv ALLOCATE(reallocate_hnv(n)) END FUNCTION reallocate_hnv

Fixed on trunk but,sadly, not on 4.1 because divergences have become too great. Paul
