The following code ICEs at -O2 on amd64. It was reduced from galgel,
which is broken at the moment because of this bug.
SUBROUTINE FOO (N, A, LDA, X, INCX)
INTEGER :: INCX, LDA, N
REAL*8 :: A(LDA,*), X(*)
REAL*8 :: TEMP
INTEGER :: I, J, IX, JX, KX
IF (INCX == 1) THEN
CONTINUE
ELSE
JX = KX + (N - 1)*INCX
DO 20, J = N, 1, -1
TEMP = X(JX)
IX = JX
DO 10, I = J - 1, 1, -1
IX = IX - INCX
TEMP = TEMP + A(I,J)*X(IX)
10 CONTINUE
X(JX) = TEMP
JX = JX - INCX
20 CONTINUE
END IF
RETURN
END

Zdenek, this is ICE in IVopts. Can you give it a look? It'd be nice
if we can get galgel to compile again.

I want to say this is a dup of bug 21963 which has a patch.

Yes it is a dup, the backtraces are identical.
