In __cxa_get_globals, the code does:

      if ((g = (__cxa_eh_globals *)
           std::malloc (sizeof (__cxa_eh_globals))) == 0
          || __gthread_setspecific (globals_key, (void *) g) != 0)
        std::terminate ();

but since __cxa_get_globals is called in __cxa_allocate_exception, the effect of this is that if the first 
exception thrown in a program is an out-of-memory exception, the program will instead call 
std::terminate, because it won't be able to allocate a new __cxa_eh_globals.  std::terminate itself 
expects __cxa_get_globals to work, so it'll call itself recursively, leading to an abort() in 
__verbose_terminate_handler.
