Hmm, 3.0-pre6e compiled with gcc-2.95.2 right out of the tar.gz
doesn't crash for me. The only thing that i can think of is to try changing
rtlinux_sigset_t rtlinux_blocked;
in psc/rtlinux_signal.c to
rtlinux_sigset_t rtlinux_blocked = {0,};
(this fix should also be in the next release of RTLinux).
This really shouldn't make a difference, though, as the signal set should be
zeroed out by rtlinux_sigemptyset() on line 31 of rtlsigtimer_app.c. What
version of gcc and the kernel are you using?

RTLINUX_SA_ONESHOT and RTLINUX_SA_RESETHAND are the same; to get a
periodic timer set the sa_flags of your rtlinux_sigaction to 0. i will fix
the timer test (rtlsigtimer_app.c) to reflect this, as well as the logic
problems.
