+``Initialization order checking``
+---------------------------------
+
+AddressSanitizer can optionally detect dynamic initialization order problems,
+when initialization of globals defined in one translation unit uses
+globals defined in another translation unit. To enable this check at runtime,
+you should set environment variable
+``ASAN_OPTIONS=check_initialization_order=1``.
