Message-ID: <bug-49885-4@http.gcc.gnu.org/bugzilla/> (raw)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49885

           Summary: Segmentation fault when writing to an automatic
                    character array
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libfortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mathewc@nag.co.uk

> gfortran --version
GNU Fortran (GCC) 4.7.0 20110723 (experimental)

> cat gf.f90
subroutine s(nb)
  integer :: nb
  character (max(80,nb)) :: bad_rec(1)
  write (bad_rec,'(I1)') 0
end
call s(10)
end

> gfortran gf.f90 ; ./a.out
Segmentation fault

Note that the program executes fine if declaration for bad_rec is changed to
any of:

  character (nb) :: bad_rec(1)
  character (max(80,nb)) :: bad_rec
