So, I enhaced foo.el to use network processes and now I can finally
reproduce it.

All you have to do is

  src/emacs -Q -L path/to/company-mode -l company -l foo.el -f foo-test-bug
  
A company tooltip should popup.  Type C-g.  The expected behaviour is to
exit the tooltip.  If it does, erase the "foo" and type "f o o" again
until it appears.

Previously, I needed to move down and up a quickly with my right hand on
the arrow, quickly pressing C-g on the left hand.  That doesn't seem to
be needed now for some reason.

Anyway, hopefully this should help you freeze Emacs.
