Maybe I should have explained here that by "narrowed down", I mean that I
can compile just ip_output() from linux-2.2.5/net/ipv4/ip_output.c with  
egcs, and the rest of the kernel with gcc-2.7.2, and reproduce a buggy    
kernel.  Examining the code produced by egcs makes me suspect the memcpy.

This was using cvs Apr 12 12:30 UTC.  I guess there still is a possibility
of some dependent egcs file not being remade for some reason.

(Oh yeah, anyone who wants preprocessed files etc., just email me and I'll
happily send them to you.)
