[Bug fortran/25813] New: EXTERNAL statement cause ICE in trans-decl.c

[kargl at gcc dot gnu dot org]

The following code is invalid due to the "external sin" line.  Nonetheless,
we get an ICE.

kargl[255] gfc4x -o z v.f90
v.f90: In function 'MAIN__':
v.f90:2: internal compiler error: in build_function_decl, at
fortran/trans-decl.c:1131

program a
  external sin
  print *, sin()
  contains
   integer function sin ()
     sin = 1
   end function sin
end program a
