GCC 8 has added checks that fail when compiling the Mar2018 branch of MonetDB with optimizations enabled. They are in fact false positives (code that will never be executed), but the compiler doesn't know that. The problem has been fixed in the default branch.
For now, use --disable-strict when configuring on Fedora 28.

Compiling from Mar2018 branch, today's hg tip, with production settings:
--disable-debug --disable-developer --disable-assert --enable-optimize
Fails with this on Fedora 28:

(same error in several files)
Compiling with debug settings succeeds: --enable-debug --enable-developer --enable-assert --disable-optimize
Is this reproducible or has it something to do with my machine?
