Comment(by zdeqb):

 I'm trying to refresh my memory here, so I may be a bit off, but:

 The reason for the crash, is that {{{args}}} on x86_64 is an array, not a
 pointer, as on i386 (and other platforms), per [1].

 va_copy could be used, but that's C99, and, if I remember correctly, C89
 is aimed for.

 Some automake/autoconf magic could also be used...

 I put together a patch [2], which, using copy-and-paste bypassed the need
 for passing a va_list around, but it's not exactly a ''fix'' (I last
 looked at the patch a month ago, but I think it worked... if it doesn't, I
 wouldn't be too surprised)

 I'll take another look at this, when I have some time... but if someone
 fixes it before me, I won't complain ;-)
