It means that some object inherited by test_patch_pc, the auto
object perhaps, is more recent than test_patch_pc itself.  There
is nothing you can do to avoid this, other than regenerating
test_pc_patch every time you recompile the auto object :)

Inside the kfun:

    if (strcmp(f->obj->chain.name, "foo/bar/gnu") != 0) { /* no leading / */
        error("Illegal call");
    }
