	# On musl, it's required that either gjs, pixman or gnome-shell to be built
	# with a larger stack otherwise librsvg fails to render a particular SVG, as
	# a result we fail to get gdm or gnome-shell running (greeted with a fail
	# whale screen). The bug has been reported to librsvg. This is ideally just
	# a temporary workaround until we understand what exactly needs a larger
	# stack size, as it's not sufficient to do just librsvg.
