Hey Jean,

I am copying this to the NOS-BBS list for others using PI 3 (Cortex A53) :

My original suggestion actually works, but I was not clear or did not
quite explain the proper way to run the JNOS binary, here is how :

    cd /usr/local/bin/Jnos

    LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libarmmem-v6l.so ./jnos

This after having removed the file, /etc/ld.so.preload

So for now, we want to make sure JNOS is using armv6 memory libs.

The preload file was automatically loading armv7 and they are problematic !
   (I don't claim to understand why, but there were some forum posts 
about this)

Compile was nothing special, default settings. I have left the -g debug 
in place.

I installed telnet by the way, then telneted to your JNOS 
( using
the nntp port 119, no problem, the banner came up, typing help, typing 
list, and
all that seems to work. No bus errors, no seg faults.
