Shaun,

thank you for pointing me in the right direction.
Moreover compiling with the native flag enabled does not solved the 
problem but helped me to try other ways. Starting from this idea I've 
changed some KVM client parameters and I've found a partial working 
solution. Here are the details of the steps I did (they probably could 
be useful to someone other).

- Force the KVM to simulate a Pentium II processor
This trick allowed me to have Asterisk running since the chan_sip module 
load, then crashed. Running the gdb I've found the problem seems related 
to the line 34490 of chan_sip.c

- Commented out the line on chan_sip.c
I don't know the details for that but I think is something related to 
the websockets feature I don't need on my tests... so I've commented out 
this line:

     //ast_websocket_add_protocol("sip", sip_websocket_callback);

and chan_sip started to load.

- Other crashes are located on some other modules I don't need on my 
tests, so I ended up to add a set of noload statements for these modules:

chan_iax2.so
app_stack.so
res_ari_events.so

I don't know if the crashes on these modules are related to the same 
problem.

After these modifications I was able to run some calls between 
extensions and queues.

I've rebuilt the whole Asterisk 12 with and without the 
CFLAGS=-mtune=native and I've tried to enable/disable the BUILD_NATIVE 
flag from menuselect having the same results.


Thank you for your help.
Best regards,

Marco Signorini.
