Thanks Dmitry! I will add tests in the future like you showed.
I have a few more traces where I observe flags even when running the
trace with -Xraw. Here are a few:
rt_tgsigqueueinfo(13471, 13471, SIG_0, {}) = 0
rt_sigsuspend([QUIT], 8) = ? ERESTARTNOHAND (To be restarted if no handler)
rt_sigaction(SIG_0, {sa_handler=0x20000080, sa_mask=[BUS FPE PWR],
sa_flags=0}, 0x20000240, 16107701032088221702) = -1 EINVAL (Invalid
argument)
Would you say that the QUIT, SIG_0, sa_mask=[BUS FPE PWR] flags should
be raw values under -Xraw? Furthermore, should sa_mask=[BUS FPE PWR]
be an integer?
Regards,
Shankara
