[Bug fortran/34719] New: N_GSYM stabs warning with common blocks on Mac OS X Leopard

["dojo at masterleep dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Under Mac OS X Leopard using the prepackaged gfortran binaries from 12/31/2007,
any fortran program with a common block emits a N_GSYM stabs warning when
compiled in debug mode.  This is with the Leopard version of XCode (3.0).

$ cat test.f
        program test
        common nrange
        call firmssh(1)
        end

        subroutine firmssh(curmax)
        common nrange
        return
        end
$ gfortran -g -c test.f
$ gfortran test.o
can't find atom for N_GSYM stabs nrange:G(0,5) in test.o
can't find atom for N_GSYM stabs nrange:G(0,5) in test.o
ld: warning, duplicate dylib /usr/local/gfortran/lib/libgcc_s.1.dylib
