AFAICT, it doesn't freeze, it eats up memory like crazy.  If you limit
the memory available to the process to some reasonable value, Emacs
will soon enough tell you that memory is exhausted, and will suggest
to save the buffer and exit.

Yuan, can you look into this, please?  I'm not sure it's an Emacs bug,
but who knows?
