I encountered this on a Raspberry Pi 2 running a minimal Ubuntu 16.04. The initial install was based on ubuntu-16.04-preinstalled-server-armhf+raspi2.img.xz from https://wiki.ubuntu.com/ARM/RaspberryPi.
Starting chromium-browser 50.0.2661.102-0ubuntu0.16.04.1 (armhf) with no args, I get:

The InitializeSandbox() error here (along with the pthread_getattr_np error above) appears to be unrelated to this crash. Running `chromium-browser --disable-gpu --no-sandbox --single-process` avoids calling InitializeSandbox() from the GPU process, since there's no GPU acceleration, no sandbox, and only one process, yet it segfaults all the same:
