BT from gdb for the WebProcess

I'm using WebKitGtk+ with my own JHBuild setting:

Epiphany 3.20.6 and WebKit 2.15.3

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

The compilation was done with CMake args:


After visiting several pages, eventually, the WebProcess hits a SIGSEV.

This bug is not reproducible in a predictable way.

I think you can use sizeof(uniRect) instead of the magic number 8.
