Are  you sure you are building sis and gdb from RSB head? sis in the
regular gdb does not support leon2 yet.
To advance things, you can send me your application binary and I can run
it in the simulator and send you the traces. If you are on 64-bit ubuntu
16.04, I can also provide you with binaries for sis/gdb, or the whole RSB.
