It looks like it is a Fedora 28 issue. I had a fedora 25 workstation vm that I built pike 8.0.498, and it worked fine. Then I upgrade to fedora 26 and built, then fedora 27 and built. Everything worked until fedora 28.  So not a pike issue, but something with fedora 28, perhaps gcc or glibc or something.
I'm going to try to debug further. Thanks... On Saturday, May 12, 2018, 6:12:45 AM EDT, Tobias S.

Before all else, I would try again from a clean checkout, i.e. make distclean git clean -xf
