nanoprobe appears to be just mirroring the error message from cma, as it
doesn't crash itself. nanoprobe seems to just carry on. Here are some logs:

https://jamielinux.com/pub/strace-cma.txt
https://jamielinux.com/pub/backtrace-cma.txt

https://jamielinux.com/pub/backtrace-nanoprobe.txt


(Another odd thing is that both cma and nanoprobe output debug messages
by default when on EPEL 6 even without passing "-d" option.)


Kind regards,
