43 CORE for the core's general use.
44 TOOL for the tool to use (and the only one it uses).
45 DINFO for debug info (symbols, line #s, CFI, etc) storage.
46 CLIENT for the client's mallocs/frees, if the tool replaces glibc's
47 malloc() et al -- redzone size is chosen by the tool.
48 DEMANGLE for the C++ demangler.
49 EXECTXT for storing ExeContexts.
50 ERRORS for storing CoreErrors.
51 TTAUX for storing TT/TC auxiliary structures (address range
54 When adding a new arena, remember also to add it to ensure_mm_init().
