coredump

I got coredump for process only at the end of scanning:

#0  0x0000000800968931 in pthread_sigmask () from /lib/libthr.so.3

#8  0x0000000000404492 in main ()

And same errors I got some times in another apps.
Not sure, may be this starts after upgrade to ryzen.

I have no idea why and what syscall missed in your system.
And why my system not crash without kib patch.
