I've been tinkering with this and I *think* the issue is with the hook I 
added at global scope:

  (add-hook 'c-mode-hook (lambda () (c-toggle-comment-style -1)))

In the attached patch, I moved this into a fixture function for the 
`whitespace-chomping-dont-cross-comments' test and it works for me (i.e. 
electric-tests pass both with and without byte-compilation). Hopefully 
this resolves the issue, though I'm unclear on *why* this was occurring 
in the first place; maybe there's a bug in the byte-compiler...?

(As an aside, I vaguely recall adding that hook at global scope because 
multiple tests failed without it, but it was a while since I wrote that 
patch and I may be misremembering. In any case, it seems that at least 
today, changing the comment style is only needed for that one test, so I 
think it makes sense to do it in a fixture solely for that test.)
