+/** \file
+ * Heap debugging functions (interface).
+ *
+ * Based on memdebug.h from curl (see below), with the following modifications:
+ *
+ * - renamed functions from curl_ to memdebug_
+ * - added memdebug_strndup
+ * - added guard bytes before and after each block to help detect overflows
+ * - if a guard byte is corrupted during free, dumps the DA to file
