ccn-lite-fetch memory corrupion

[MahdiBaghbani]

freeing a pointer causes memory corruption in ccn-lite-fetch

here in code:

ccn-lite/src/ccnl-utils/src/ccn-lite-fetch.c

Lines 137 to 141 in da0d9de

	*prefix = ccnl_prefix_dup(pkt->pfx);
	*lastchunknum = pkt->val.final_block_id;
	*content = pkt->content;
	*contentlen = pkt->contlen;
	ccnl_pkt_free(pkt);

assigning content and content length pointer values from pkt to external pointers and then freeing the pkt itself also removes the pointers pointing to the memory location and causes memory corruption and garbage output from any write operation:

ccn-lite/src/ccnl-utils/src/ccn-lite-fetch.c

Line 360 in da0d9de

write(1, content, contlen);

possible solution would be passing the pkt itself out of function and free it after write function
