when compiling the attached test file, you can see that the debugging test
needs 
	8 min!  with g++-3.4.1
Every other test including g++-3.3.3 needs only some seconds.

Defining __DEBUGGING__ 
enables the usage of std::cerr, which happens at the end of the attached file.

My system is a Dual Pentium III 550 with linux-2.4.26

Regards Andre
