These ICEs which I saw yesterday may be boiled down to the following out of
context fragment which continues to fail on i[56]86. Unlike the complete
version, I can assign this to FSF:
subroutine dobug(xdata ,xin,ndata,nxy)
real xdata (ndata ),xin(nxy)
i= 1
j= 2
dowhile(xin(i) > xdata (j))
j= j+1
enddo
return
end
