When compiled with -O3 the following code ICEs on amd64-linux.
parameter(numlev=3,numoblev=1000)
integer i_otyp(numoblev,numlev), i_styp(numoblev,numlev)
logical l_numob(numoblev,numlev)
do ixe=1,numoblev
do iye=1,numlev
i_otyp(ixe,iye)=0
i_styp(ixe,iye)=0
l_numob(ixe,iye)=.false.
enddo
enddo
do i=1,m
do j=1,n
if (l_numob(i,j)) then
write(20,'(7I4,F12.2,4F16.10)') i_otyp(i,j),i_styp(i,j)
endif
enddo
enddo
end

------- Comment #1 from dominiq at lps dot ens dot fr 2010-08-05 21:11 -------
Confirmed on x86_64-apple-darwin10 (for both -m32 and -m64) and the code
compiles with -O2 -ftree-vectorize. Revision 162490 is OK.
