I'm *guessing* you are using a downlevel Valgrind package like debian-3.10.1-... You need Valgrind 3.11 for the most complete ARM/ARM64 support. Here's a Debian package that produced a similar finding on me earlier today with a LeMaker HiKey (http://www.amazon.com/dp/B019O3QTSA): # apt-cache show valgrind Package: valgrind Version: 1:3.10.0-4 Installed-Size: 49816 Maintainer: Alessandro Ghedini <gh...@debian.org> Architecture: arm64 Replaces: valgrind-dev ...
