full gdb backtrace of WebKitWebProcess

Hello,

I'm running a gtk3 app inside an Ubuntu docker container that load a page via WebKit and creates a snapshot of it.

The problem I have is that in some web pages, the app would terminate with a SIGBUS signal. I've provided an attachment with the apps backtrace. The interesting thing is that the exact same app doesn't fail on the host system that much often as it does when inside Docker

Software used:
- x86-64 Ubuntu 16.04.1 on host
- phusion/baseimage as container baseimage 
- Docker 1.12.3
- a build of webkitgtk 2.14.4
- cairo master @ cffa452f44eadebef8553502e3d6cc49829d38ce
