Full stack trace of the crash including the error.

Apple Silicon native builds. Intel builds do not crash when run on an Apple Silicon Mac using Rosetta2. Although the attached debug information is generated with today's main HEAD (commit 3d71b7e95dde) on macOS 13.1 developer's beta 3 this crash also happens with WebKitGtk 2.32.0 on every version of macOS from 11 on.

Note that there are three patches needed to successfully build WebKitGtk; I'll attach them shortly.

Dependencies are all current git clones from the respective repositories; Gtk is gtk-3-24; most everything else is main/master. Builds are with the [gtk-osx unstable moduleset](https://gitlab.gnome.org/GNOME/gtk-osx/-/tree/master/modulesets-unstable).
