I just did some quick debugging and I only have a very limited understanding of the code in question but it seems that the 'continue' in line 445 without increasing 'buf_idx' might cause the problem. In one debugging session when the crash occurred the value of 'buf_idx' was 2 and the value of 'pkt_idx' was 8965. Any help with this issue would be greatly appreciated. If you need any further information just let me know. Martin
