The problem definitely exists and is not a problem of CEDET/Semantic.

Here is a minimal example to reproduce the failure:

,----[ test.el ]
| (progn
|   (require 'cc-mode))
`----

$ emacs -Q test.el
M-x eval-buffer

This will result in an error: Invalid read syntax: ")"


The error disappears if the expression is in one line:

,----[ test.el ]
| (progn (require 'cc-mode))
`----
