[CppAD] possible memory leak

[Jochen Siehr]

Hi,

I've been using the svn-Repository of CppAD for quite a while. The 
results for my small test example using valgrind for memory check with 
CppAD revision 1947 (2011-05-12 05:09:07) are fine:

************************************************************************

Using revision 1948 or later the result is:

************************************************************************

************************************************************************

So there seems to be a memory leak. It would be nice, if this could be 
fixed.

Regards,
Jochen
