Build ID: 20170907-1650_eclipse-cpp-oxygen-1-RC3-linux.gtk.x86_64.tar.gz
Host: Ubuntu 16.04.2 on Virtualbox 5.1.26, 3D acceleration + guest utilities on
GTK: libwebkit2gtk-4.0-37:amd64                 2.16.6-0ubuntu0.16.04.1

Eclipse crashed hard on me with attached hs_err_pid20835.log , here are the top frames from the stack:

The issue is not reproducible, but here's the steps I had performed:
1. Launch Eclipse, close the welcome screen (Note: Welcome screen is empty)
2. Import a C/C++ project, allow it to be fully indexed
3. Launch a GDB debug session
4. Window > Preferences, enable the Oomph Preference Recorder
5. Preferences:Filter:GDB, Enable "GDB Traces", click "Apply and Close"

--> The Oomph confirmation dialog briefly appeared
--> Then an Ubuntu dialog said "WebKitNetworkProcess died" and Eclipse was gone
