Follow-up Comment #11, bug #47334 (project lwip):

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

Hi, as stated the crashes occur rarely and after Ivans comment I assume it
could be related to my low-level driver I'm using. However, it is still odd
that I need 9 KB of RAM just to receive 1 KB sized fragmented packets at all
(and not be discarded since there is no space left to allocate them, at least
that's what I observed when I debugged this).
