native: segfault on heavy network usage in transceiver #499
Description
sending >100 packets per second causes a segfault in RIOT
in 9 of 10 cases it's:
Core was generated by `../projects/ccn-lite-client/bin/native/ccn-lite-client.elf grid5x5_b4 -t 4711 -'.
Program terminated with signal 11, Segmentation fault.
#0 0x08051cb1 in run () at transceiver.c:269
269 response = send_packet(cmd->transceivers, cmd->data);
Missing separate debuginfos, use: debuginfo-install glibc-2.17-20.fc19.i686

This looks strange, because receive_packet with type argument=0 indicates it's a packet from CC1100 transceiver. So this might be a corrupted stack
