--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Revision r195570 (2013-01-30) gives the errors without ICE, r195694 gives the
ICE, likely r195684.

Note that r220452 (5.0) gives

pr65045.f90:3:6: Error: Symbol at (1) is not appropriate for an expression
pr65045.f90:5:7:

    else
       1
Error: Unexpected ELSE statement at (1)
pr65045.f90:6:6: Error: 'i' at (1) is not a variable
pr65045.f90:7:6:

    end if
      1
Error: Expecting END BLOCK statement at (1)
(null):0: confused by earlier errors, bailing out

The reduced test

real :: i = 9.9
i:block
 if (i>7.7) then
     exit i
   end if
end block i
end

gives

pr65045_db_1.f90:3.6:

 if (i>7.7) then
      1

   end if

Looks good to me - okay with a test case and a ChangeLog.
