Thanks for your quick answer Steven.

I don't think it's undefined behavior (but I may be wrong of course :). 
Everything works fine, the program run as I expect when I only test all 
the graph stuff.

I attached some code (the makefile is generated by Qt4). As you will 
probably see if you compile and execute, a test fails. But if I comment 
the tests in TreeTesting.cxx, everything run smoothely, but the previous 
error was not related to the commented piece of code.
