I'm guessing this is a seccomp sandbox violation. Unfortunately debugging
these can be a bit tricky. There are some instructions at the top of
sandbox-seccomp.c if you want to give it a try but unfortunately the
need some handholding because some change between glibc and the Linux
kernel headers causes them to fail on some systems.
