So I looked into it, and there’s at least one thing wrong: the test must
be compiled with #:partial-eval? #f, otherwise the ‘let’ vanishes, which
defeats the test.
Second thing, it suffices to insert a function call like
((lambda (x) #f) #f) just before calls to ‘gc’ to solve the problem.
So I’m thinking we may have a real bug here.
I’ve changed the test this way:
(pass-if "Lexical vars are collectable"
(pair?
(compile
'(begin
(define guardian (make-guardian))
(let ((f (list 1 2 3)))
(guardian f))
;; Note: no `stack-cleanup' call should be needed here since
;; leaving `let' should have the same effect.
;((lambda (x) x) #f)
(gc)(gc)(gc)
(guardian))
;; Turn the partial evaluator off so that `let' is preserved.
#:opts '(#:partial-eval? #f)
#:env (current-module))))
The assembly code does seem to push ‘void’ in all cases, though, but
this needs to be double-checked.
Thanks,
Ludo’.
