* [Bug libstdc++/24025] New: libstdc++ crashes when out of memory exception thrown

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.

Adding Rth in CC as the author of the fix of libstdc++/10606, which added the
call of __cxa_get_globals from __cxa_allocate_exception
