Looks like a problem with the byte compiler/bytecode interpreter,
because both loading bubbles.el from the master branch and loading
bubbles.elc from the release branch works just fine.  Also, if I run
Emacs 25.2 on bubbles.elc from master, Emacs complains about an
invalid bytecode.

Vibhav, could this have anything to do with the latest changes in
bytecode?
