And GCC tells you so:

manuel@gcc12:~$ ~/trunk/186353M/build/gcc/cc1 -Wall tmp.c 
tmp.c:3:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
 void main()
      ^
tmp.c: In function ‘main’:
tmp.c:8:8: warning: ‘prod_vg’ is used uninitialized in this function
[-Wuninitialized]
   multg(prod_vg);
        ^

Now that -Wuninitialized is separated from -Wmaybe-uninitialized, maybe it is
time to enable it by default.
