No, that is not infinite, just an important depth of templates recursions. 
Your 
compiler seems particularly bad at dealing with debugging informations. You 
should try to tweak the debugging options in debug mode, to reduce the memory 
consumption.

This example examples/Mesh_3/mesh_polyhedral_domain.cpp has been compiled in 
debug mode by the CGAL testsuite, each day. The compiler was MSVC2008, 
though. 
Maybe MSVC2005 has difficulties with it. Do you have access to MSVS2008?
