app-portage/eix: Build with upstream's CXXFLAGS/LDFLAGS for debugging support; not recommended for normal use.
dev-util/google-perftools:
Build a set of libraries with debug support (so-called
debugalloc). These are available by default but are not needed
unless you're actually developing using tcmalloc.
media-libs/vapoursynth: Enable compilation options required for debugging
net-p2p/transmission: Enable assertions
net-vpn/amneziawg-modules: Enable verbose debug reporting in dmesg of various AmneziaWG peer and device information.
