.init_array is used by newer versions of gcc to serve the same purpose
as .ctors, but using a different mechanism to run constructor code.
Similarly for .fini_array. At a guess, your code is making
assumptions about the order in which destructors are run. If you
google for "g++ static destructor order" you'll find lots of other
people with the same problem.
