Did my reply get lost ?
It's a known problem.  It's because of
`font-lock-beginning-of-syntax-function' which is set to
`beginning-of-defun' in CC modes.  It's the exact same problem as when
you put an open-paren in column 0 in an elisp docstring.
I.e. the problem in the guy's code is not that he has a \\\n inside
a string, but that he has \n( inside his string.

Setting font-lock-beginning-of-syntax-function to nil will fix the
problem (and occasionally slow down font-lock substantially).
