           Summary: [4.3/4.4/4.5/4.6 Regression] Segfault with SUM of
                    zero-sized array
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org


Reported on IRC. The following program segfaults with gfortran 4.3 to 4.6 but
works with gfortran 4.1:

program p
  real(8) :: empty(0, 3), square(0)
  square = sum(empty * empty, 2)
  print *, "square=", square
end

The "Bus error" seems fixed by the patch in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43829#c32.

Well, it does not fix it, it just hides the problem: The patch in PR 43829
moves SUM into the front end - thus, it makes the libgfortran code unreachable
for this test case.

For completeness, the submitted asked at c.l.f whether the program is valid;
Richard Maine thinks so. (I concur ;-)

Of course, the patch does not work as "dest" is not NULL ...

I wonder whether a patch like the following would be correct. One probably
needs to go through all the users of ifunction{,_logical}.m4 and check what is
the correct solution, which might or might not be the one below:
