--- Comment #3 from anlauf at gcc dot gnu.org ---
Reduced testcase:
program test
implicit none
integer, parameter :: m=2, n=3
real, allocatable :: r(:,:)
allocate (r(m,n))
write(*,*) r(m+1,:)
write(*,*) r(m+1,1)
end
Looking at the tree dump, there are array bounds checks generated for both
dimensions in the latter write, but there are suspiciously looking checks
for dimension 2 for the first case (r(m+1,:)).
