I don't have a good testcase at hand (it's just a matter of time, though), but
at least the following snippet makes the current trunk ICE:
subroutine kc (IX, L4, PQ)
integer VT, DK, L4, IX, F0
real PQ (L4, L4)
F0 = VT
0010 do VT = 1, 2
end do
if (IX .eq. 0) go to 0020
do VT = 1, L4
end do
go to 0010
0020 do VT = 1, L4
if (VT .ge. 0 .and. VT .le. F0) go to 0030
do DK = VT, L4
PQ (VT, DK) = 0.0
end do
0030 end do
return
end
