Robert,
I applied the patch, re-make, re-generate mib2c for etherStatsTable.
It's still broke, but at different place "Broken pipe". Please see the debug messages below:
$ snmpwalk localhost etherStatsTable

I don't know how I haven't run across this in my testing, but I did track it
down. The length in the get function is supposed to be in bytes, and the
memcpy does take that into account. However, the size check at the top of the
function does not, thus the memcpy is overwriting the buffer. This will only
happen for objects that exceed the default buffer size (40 bytes).
Here is a patch that should fix this. Let me know if you still have problems...

You are lost in a twisty maze of little standards, all different.
