I think you'll need to tack
CFLAGS+=-g
STRIP=
to the end of the Makefile and get a trace :-/ The IPCP error is the
result of the peer sending an IP packet before authentication is
complete (a ``set log physical debug'' may be interesting here).
The same log level may also tell us more about the nat_LayerPull().
I suspect the core dump may be nothing to do with these warnings
though....
