Hmm, I'm seeing a new ICE that could be related to your patch:

        function rombint()
        implicit none
        real :: rombint
        integer :: i, j
        real :: g(6), g0, g1

10        i=i+1
          if (i.gt.20) go to 40
            do 30 j=1,6
            g1=g0+g(j)
            g0=g1
30        continue
        go to 10
40      rombint=g0
        end function rombint

~/tmp>gfortran -c -O bug.f90 
bug.f90: In function 'rombint':
bug.f90:1: internal compiler error: in n_of_executions_at_least, at
