Error: an illegal memory access was encountered

I think that the problem you are having is that you create the cylinder as a local variable in fill_parts(), so it gets destroyed at the end of the function. Try making the cylinder a member of the class instead.

I tried to duplicate the pattern of defining objects like what exists in "OdeObjects" example (because I am totally newbie in GPUSPH!). So, why the objects in OdeObjects examples are not destroyed and the example runs well?

[Oblomov]

Because in OdeObjects the Sphere and Cylinder are declared as members of the class (see OdeObjects.h), and only initialized in fill_parts(); hence, the object persists as long as OdeObjects is instantiated (which is throughout the whole simulation). Instead, in your example you declare the object in fill_parts(), so by C++ scoping rules it gets destroyed at the end of the function.

I already declared the cylinder in the header file (look at the Gprobe.hh file in the repository I created). However for being sure, even I declared the parameters for mass, radius, ect of cylinder in the header and assigned them in the class of the example in the cc file (not in the fill_parts() ).
However, I still get this error.

Maybe I am doing something like newbie mistake!?

If it's still segfaulting you'll have to compile the host code in debug mode (add a CXXFLAGS=-g to your Makefile.local, then run a make cpuclean and then make again) and use gdb to track the cause of segmentation fault.
