This costs code size for the call to xmalloc. + - Put them on stack. For some very small machines with limited stack + space, this can be deadly. For most folks, this works just fine. + - Put them in BSS. This works beautifully for computers with a real + MMU (and OS support), but wastes runtime RAM for uCLinux.

Electric + fence is another very useful malloc debugging library which uses + your computer's virtual memory hardware to detect illegal memory + accesses.
