Hi Mario,

You are right, PointSetDemo.exe seems statically linked to boot and cgal 
(according to depends.exe). I would be surprised that this makes any 
difference.

CGAL 4.1 or 4.2 should be fine too.

CGAL does not depend of Windows XP. My guess is that your application 
works in XP compatibility mode only by chance (although I may be wrong: 
I do not know exactly what the XP compatibility mode does).

I would recommend you to try next things:

1) Check that your application and the libraries it uses (including 
CGAL) are compiled with the same Windows runtime. Mixing Windows runtime 
may lead to very strange bugs.
As far as I remember, the Release target should use the Multithreaded 
Dynamic Dll runtime (/MD) and the Debug target Debug Multithreaded 
Dynamic Dll runtime (/MDd).
Usually, Visual Studio complains when you try to link an application and 
libraries that mix several runtimes.

2) If your application is a command line application, you may activate 
traces.
To turn on traces in your application, you should add the next line in 
your application's CMakeList.txt
 ADD_DEFINITIONS( "-DDEBUG_TRACE" ) # turn on traces
then recompile it with Visual Studio (debug version).
Then please run again your application (debug version) to reproduce the 
problem, and post its output in cgal-discuss.

3) I invite you to use a memory debugger (e.g. Valgrind on Unix or 
AQTime on Windows) to nail down the problem.

Best regards,
Laurent Saboret
