Well, false alarm, possibly.
It turns out that valgrind won't work yet with the new
compressed DWARF that gcc is generating, so something to
watch out for if you're using Rawhide. (I also noticed
that gdb had problems, although it didn't segfault).

If you have the latest Rawhide, could you try the very simple test
described in the comment?
You will need to install the latest 'systemd' & 'systemd-debuginfo'
packages; my suspicion is that the latter is broken.
