ind_offset is already a sizeof() measure, isn't it?
I would guess that what you want is

>  *((long long int *) ((char *)ind + ind_offset*act_tuple)) = variable->len;

since ind_offset*act_tuple is a number expressed in bytes, and should
not be scaled up by sizeof(long long int).

Also, if the code works for you at all, it's because GCC is (in
violation of the ANSI C standard) interpreting the construct as
addition to char* rather than addition to void*.  Casting to anything
other than char* will change the behavior.

(Might be a lot easier just to declare ind as char* instead of void*
in the first place...)
