#2071 seems to have fixed native interrupt handling. But I can still crash a riot native instance by flood pinging.

Steps to reproduce:

1. run gnrc_networking
2. start a couple (5-10) ping -f <riot-ip>%tap0
3. wait some minutes

Sometimes it takes 30sec, sometimes 5min, but riot reliably crashes.

The problem seems somewhere in gnrc, as my other stack runs fine since #2071 is merged.
Here's a backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x0804df49 in gnrc_pktbuf_start_write ()
(gdb) bt

Edit: summary of reasons why this might not be a GNRC issue in #6123 (comment).
