I don't think plagiarism is the concern.  The conern is that
copy/paste of blocks of code where the pasted block needs to be
updated in several places, but not all of the updates were performed.

Coverity can detect such instances, for instance.

Here is an article from 2006 describing such a tool:

Wikipedia says PMD has a copy/paste detector that works with C++:
<http://en.wikipedia.org/wiki/PMD_(software)#Copy.2FPaste_Detector_.28CPD.29>

"Note that CPD works with Java, JSP, C, C++, C#, Fortran and PHP code.
Your own language is missing ? See how to add it here"
