------- Comment #3 from dominiq at lps dot ens dot fr 2009-04-29 14:19 -------
I have modified the code referenced in pr36683 as:
PROGRAM calls
IMPLICIT NONE
INTEGER :: a(2), b(3), c(6), n , i
c = myfunc(a,b)
WRITE(*,*) "c:",c !! gives "c: 1 2 3 4 5 6"
n = 5
c = 0
c(1:n) = (/(i+2,i=0,n)/)/myfunc(a,b)
WRITE(*,*) "c:",c !! gives "c: 1 2 3 4 5 0"
CONTAINS
FUNCTION myfunc(v1,v2) RESULT(v3)
IMPLICIT NONE
INTEGER, INTENT(IN) :: v1(:), v2(:)
INTEGER :: v3(SIZE(v1,1)*SIZE(v2,1))
INTEGER :: i, j, k
DO i=1,SIZE(v1,1)
DO j=1,SIZE(v2,1)
k = (i-1)*SIZE(v2,1) + j
v3(k) = k
ENDDO
ENDDO
WRITE(*,*) "myfunc: v3:",v3 !! always gives "v3: 1 2 3 4 5 6"
END FUNCTION myfunc
END PROGRAM calls
and I don't get any run time error even with '-fbounds-check'.
This confirms that this pr is a duplicate of pr36683.

I wonder if this not a duplicate of pr36683.

------- Comment #1 from pault at gcc dot gnu dot org 2009-03-08 16:07 -------
Confirmed.
For some reason, we have never added a bounds check to assignments. The first
testcase uses a check internal to the function. Once an extra expression is
added to the rhs, there is nothing to check against.
Cheers
Paul
