Minimal test case:

  subroutine one()
  end subroutine one

compiled with gfortran -finstrument-functions. Valgrind shows:

==4467== Invalid read of size 2
==4467==at 0x76C5C4: gimple_build_call (gimple.c:262)
==4467==by 0x7A1DB8: gimplify_function_tree (gimplify.c:7938)
==4467==by 0x642EA7: cgraph_analyze_function (cgraphunit.c:890)
==4467==by 0x643697: cgraph_analyze_functions (cgraphunit.c:1108)
==4467==by 0x645544: cgraph_finalize_compilation_unit (cgraphunit.c:1294)
==4467==by 0x7F1C3C: write_global_declarations (langhooks.c:303)
==4467==by 0x8E9283: toplev_main (toplev.c:564)
==4467==by 0x645200C: (below main) (libc-start.c:226)

The ICE occurs in gimple_build_call (gimple.c:262) for:
  gcc_assert (TREE_CODE (fn) == FUNCTION_DECL || is_gimple_call_addr (fn));
The problem is that the argument is fn == NULL.


The callee (gimplify_function_tree (gimplify.c:7938)) is:

  x = implicit_built_in_decls[BUILT_IN_RETURN_ADDRESS];
  call = gimple_build_call (x, 1, integer_zero_node);

The problem is that  implicit_built_in_decls[BUILT_IN_RETURN_ADDRESS]  is NULL.
