[Bug fortran/25024] New: ICE with external declaration inside same procedure

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

The following simple procedure causes an ICE:

      subroutine   A()
      EXTERNAL A
      END

Error message with compiler "gcc version 4.2.0 20051124 (experimental)" is:

crash2.f:0: internal compiler error: in build_function_decl, at
fortran/trans-decl.c:1114

With compiler "gcc version 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)"
the message is essentially the same:

crash2.f:0: internal compiler error: in build_function_decl, at
fortran/trans-decl.c:1026
