The reason for the issue can be found in trans-decl.c:

gfc_get_extern_function_decl (gfc_symbol * sym)
[...]
  /* Do not use procedures that have a procedure argument because this
     can result in problems of multiple decls during inlining.  */
  proc_formal_arg = false;
  if (gsym && gsym->ns && gsym->ns->proc_name)
