it is the line that reads:
sqlda_bv->V[i-1]=(char*)v_bv_int;
V[] is an array of pointers to data. You are setting the first pointer to the number 1, not to the address of a variable that contains one. Change it to:
sqlda_bv->V[i-1]=(char*)&v_bv_int;
^^
and it won't seg fault (it may still not work, haven't looked any further but you are missing the & for sure)
