Hi all,
I'm using Xenomai 3.1.1 in cobalt mode, on x84_64.
Please consider the attached simple test code.
When I start the application, I never see the "Pipe task running"
printf.
When I close application (ctrl+c), rt_pipe_join() on pipe task hangs.
Analyzing the code with gdb, the timeout in tv structure inside
rt_pipe_read_timed() is the following
(gdb) thread 13

(gdb) print tv
$1 = {tv_sec = 1438, tv_usec = 783700}
It seems a value related to uptime (system was up by about 24 minutes,
1440 seconds, when debugging).
