           Summary: gfortran ICE with "common" in modules
           Product: gcc
           Version: tree-ssa
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: fortran
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: olchansk at panix dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

Attached valid code produces an ICE. The ICE goes away if the "common" name is
declared as integer.

P.S. Can we have the ICE print the offending variable name?

[olchansk@dork gfortran_test]$ cat test1.f90
module foo
  implicit none
  integer baz
  !integer bar  ! uncomment this line to avoid the ICE
  common/bar/ baz
end module foo
