Silly me, test_call is supposed to be
Definition test_call : bedrock_func :=
let x := "x" in
let p := "p" in
let q := "q" in
let test := "test" in
("call", ([x], [] : list string, bedrock_func_body:(
unpack! p, q = test();
store(x, q)
))).
I got the example working; sorry for the inconvenience.

I'm glad you figured out a solution that works for you. I think the following (untested) code should also work:
Definition test_call : bedrock_func :=
("test_call", (["x"], ["x"], bedrock_func_body:(
unpack! p, q = test();
x = q
))).
Instance spec_of_call : spec_of "call" := fnspec! "test_call" _x_input_unused ~> x,
{ requires t m := True;
ensures t' m' := t=t' /\ m=m' /\
word.unsigned x = 2 }.
Lemma call_correct : program_logic_goal_for_function! test_call.
Proof.
repeat straightline. straightline_call; auto. repeat straightline; subst; eauto.
Qed.
(The variable-name boilerplate is no longer required and we have dropped it e.g. here.)
