Hi,
I found out that there seems to be two similar cases in srfi-4.scm
(define u32vector-ref
(getter-with-setter
(lambda (x i) (##core#inline_allocate ("C_a_i_u32vector_ref" 4) x i))
u32vector-set!
"(chicken.srfi-4#u32vector-ref v i)"))
(define s32vector-ref
(getter-with-setter
(lambda (x i) (##core#inline_allocate ("C_a_i_s32vector_ref" 4) x i))
s32vector-set!
"(chicken.srfi-4#s32vector-ref v)))
Since C_a_i_u32vector_ref and C_a_i_s32vector_ref may end up calling
bignum1, there should probably be 5 bytes allocated instead of 4.
I found this by compiling chicken with gcc -fsanitize=address
-fsanitize=aligment, and by linking also related libraries. Address
sanitizer then reported potential problems.
