Re: [Chicken-hackers] Chicken 5.1.0 on Debian/armel architecture

Hi, there!

There definitely is something wrong on arm, but it turrns out to be hard
to reproduce, and seems like a memory-related heisenbug to me.

Can you try this test program for me?

---
(import chicken.locative chicken.gc srfi-4)
(define old (u32vector 0 1 2 4294967294 4294967295))
(define new (make-u32vector 5))
(do ((i 0 (add1 i)))
     ((= i 5))
  (let ((loc-src (make-locative old i))
        (loc-dst (make-locative new (- 5 i 1))))
    (locative-set! loc-dst (locative-ref loc-src))))
(assert (eqv? (u32vector-ref old 4) (u32vector-ref new 0)))
(gc #t)
---

Also, if the bug is somehow reproducible with a chicken
built with "DEBUGBUILD=1" and surfaces when run under gdb
(add -k when compiling the test), we could try to proceed from there.
