+/* Default shared memory map size. Most targets just need a coverage map
+   between 20-250kb. Plus there is an auto-detection feature in afl-fuzz.
+   However if a target has problematic constructors and init arrays then
+   this can fail. Hence afl-fuzz deploys a larger default map. The largest
+   map seen so far is the xlsx fuzzer for libreoffice which is 5MB.
+   At runtime this value can be overriden via AFL_MAP_SIZE.
+   Default: 8MB (defined in bytes) */
