Follow-up Comment #10:

>So that means you have 308 extra bytes allocated

Ooops, I got that wrong: struct lowpan6_reass_helper is only allocated once
per FRAG1 (not per FRAGN), so you only have 22 bytes of overhead per
fragmented IPv6 packet.

Given that, I don't know what's the issue and what's the proposed fix.

We could enforce an upper limit on allocated packets and/or fragments, but I
don't see how it would crash.
