Per https://sourceware.org/bugzilla/show_bug.cgi?id=22158 , Systemtap is broken on kernel versions > 4.14. It looks like they're aware of this in the debian package : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892995 . With Bionic Beaver about to ship with kernel 4.15 and systemtap 3.1-3, systemtap will be unusable on the LTS of Ubuntu.

[Impact]
systemtap cannot be used in Ubuntu 18.04 due to kernel ABI incompatibilities with the 4.15 based kernel.
[Test Case]
Load an example systemtap script to verify that it can be built and used with the Ubuntu 18.04 kernel.
[Regression Potential]
Low regression potential since the package does not currently work as-is.

$ sudo stap -v -e 'probe kernel.function("proc_dostring") {printf("proc_dostring() called\n"); exit()}'
In another terminal, execute 'cat /proc/sys/kernel/hostname' and the stap command should print "proc_dostring() called" and exit. See the stap-bad.txt and stap-good.txt attachments for example output.
