+/* This is a hack for ASAN

+ * exit and will show as a leak in ASAN with no stack trace (as the plugin
+ * has been unloaded from memory).
+ *
+ * The below is designed to trick the compiler into adding a "UNIQUE" symbol
+ * which can be seen using:
+ * readelf -s storage/spider/ha_spider.so | grep UNIQUE
+ *
+ * Having this symbol means that the plugin remains in memory after dlclose()
+ * has been called. Thereby letting the libraries clean up properly.
