*
* <note>
* If any call to allocate memory fails, the application is terminated.
* This also means that there is no need to check if the call succeeded.
* </note>
*
* <note>
* It's important to match g_malloc() with g_free(), plain malloc() with free(),
* and (if you're using C++) new with delete and new[] with delete[]. Otherwise
* bad things can happen, since these allocators may use different memory
* pools (and new/delete call constructors and destructors). See also
* g_mem_set_vtable().
