How do you run valgrind ? Which version  ? Do you compile luatex with standard -O2 ? --

My test were done with

(Arch) Linux, Kernel 5.0.4-arch1-1-ARCH
glibc 2.28-5
valgrind-3.14.0

The tests were done with a debug build (`./build.sh --debug`) a regular build (`./build.sh` w/o further options) and the current TeXLive pretest version.
