I found this with gfortran (gcc version 4.3.0 20070328), it seems to work with
the gfortran/gcc included in my Mandriva 2007 (gcc version 4.1.1 20060724), so
I've marked it as a regression.
$ cat test.f90
SUBROUTINE Test
IMPLICIT NONE
INTEGER :: i, j
REAL*8 :: C(3,100), rM(100), rMI
COMMON /RInfo/ rMI
DO i = 1, 3
DO j = 1, 100
rMI = C(1,j) + C(i,j)
END DO
END DO
END
$ gfortran -c -O2 -ftree-vectorize test.f90
test.f90: In function test:
test.f90:1: internal compiler error: in affine_function_equal_p, at
tree-data-ref.c:2072
Please submit a full bug report,
with preprocessed source if appropriate.
