Thanks for bringing the issue under my attention. Indeed I caused it with my forking fix. I have just committed a temporary fix, to alleviate the freezing. However, now the first LPE of a stack is forked 20 times (arbitrary max forking).
The problem is that clones increase the hrefcount on LPEObjects, while they shouldn't. So in "LivePathEffectObject::fork_private_if_necessary", "SP_OBJECT_HREFCOUNT(this) > nr_of_allowed_users" is always true. I could not find out just now why the hrefcount is increased for clones.
Work in progress... :/

This is easily a no-go for the release:
- with Pen or Pencil, draw anything in Spiro mode (any other
LPE would do the same)
clone (alt+d)
select original and try to move it by arrow key
watch Inkscape freeze and die an out-of-memory death,
apparently in some kind of infinite recursion.
I suspect this has something to do with LPE stack cloning that Johan recently worked on, but as I don't watch commits as closely as I would like lately, I also cc: others who did some nontrivial changes.
Let's get this fixed quickly :)
