+Turning off ASan annotation in containers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Struct template ``__asan_annotate_container_with_allocator`` may be used to turn off ASan annotations for containers
+with a specific allocator.
+If ``__asan_annotate_container_with_allocator<_Alloc>::value == false``, container won't be poisoned at all.
+Value may be changed by template specialization. Variable ``value`` is of type ``bool``.
+
+If you are creating allocator not working correctly with container annotations from libc++,
+a better choice may be unpoisoning memory, if possible. This way, ASan benefits are present in the program.
