Hi all, a friend of me (Trabucayre) help me to use gdb and we found that the 
problem were in openbts/Transceiver/USRPDevice.cpp at line 365 (revision 11042):
if ((currLen*2+payloadSz)<=currDataSize) 
memcpy(currData+currLen*2,tmpBuf+2,payloadSz);


Trabucayre find a solution to make program don't segfault, but we don't know if 
the integrity of it was alive:

        if ((currLen*2+payloadSz)<=currDataSize) 
                if ((readLen/4)< payloadSz+2) 
memcpy(currData+currLen*2,tmpBuf+2,payloadSz);

In my case , i launch asterisk, transceiver and finaly OpenBTS900, but how i 
can check if OpenBTS rule?

Have a nice day all ++
