[Bug fortran/23308] New: named common block confused as procedure - runtime segfault

["pault at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

There does not seem to be any check in procedure calls that an external symbol
is not a common block.

[prt@localhost mytests]# cat horrible.f90
program horrible
  integer a(10)
  common /foo/ a
  call foo ()
end program horrible[root@localhost mytests]# /gcc-4.1/bin/gfortran horrible.f90
[prt@localhost mytests]# ./a.out
Segmentation fault
