BT from gdb for the WebProcess

I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/master

Epiphany 3.20.3 and WebKit 2.15.2 with the attached patches for bug 164049, bug 165200, bug 165283 and bug 164052, applied.

I'm running Epiphany with the dconf key:

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

And the env variable:

"export LIBGL_DRI3_DISABLE=1"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'

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

This bug is not reproducible in a predictable way.
