sed: prevent overflow of length from bb_get_chunk_from_file
This fragment did not work right: temp = bb_get_chunk_from_file(fp, &len); if (temp) { /* len > 0 here, it's ok to do temp[len-1] */ char c = temp[len-1]; With "int len" _sign-extending_, temp[len-1] can refer to a wrong location if len > 0x7fffffff.
