Comment (by asandroq):

 Sorry I wasn't clear. I compiled the SVN trunk from 09/07/2007.

 version:

 {{{
 this is CHICKEN
 Version 2.705 - linux-unix-gnu-x86-64 - [ 64bit manyargs dload applyhook ]
 (c)2000-2007 Felix L. Winkelmann
 }}}

 apply-hack.x86-64.s:

 {{{
         .text

         .globl _C_do_apply_hack
         .type _C_do_apply_hack, @function

         movq %rdi, %r11         /* get proc */
         movq %rsi, %r10         /* save buffer address, before we clobber
 %rsi */
         cmpl $6, %edx           /* clamp at 6 */
         ja l2
         je l3
