IMHO this is a bug in gcc.  It should not use atexit to register the dtor
for static local objects.  Instead it should set up an entry in the .dtors
section.  There is no (standard) way to unregister an atexit function, and
implementing it would require to put a hook into libc for use by the
dynamic linker.
