Ok, that helps thanks. Now, running the latency test over GDB instead of
using the "run" script would likely give us a backtrace for the
segfault. I'd be interested to know where the latency application is
sent the fault signal. E.g.
modprobe xeno_nucleus
modprobe xeno_native
(if needed)
then,
cd /usr/xenomai/testsuite/latency
gdb latency
r
...(SIGSEGV)...
bt
