AFAICS, only x_icon can throw an error. We could arrange for removing
the failed frame from the list (and free its glyph matrices while at
that) if an error is thrown.

I agree. I asked Jason whether such a change could do any harm on
Windows.
So I understand from your response that it is okay for Fx_create_frame
to be entered recursively, yes?
