-/** \file
- * Heap debugging functions (implementation).
- *
- * Based on memdebug.c 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
