    Add note about jit_set_memory_functions call.
    
        * doc/body.texi: Add note that jit_set_memory_functions
        should be called before init_jit, because init_jit
        itself may call the memory wrappers.

 using these wrapped functions, but you must note that if lightning
 was linked to GNU binutils, malloc is probably will be called multiple
 times from there when initializing the disassembler.

+Because @code{init_jit} may call memory functions, if you need to call
address@hidden, it must be called before @code{init_jit},
+otherwise, when calling @code{finish_jit}, a pointer allocated with the
+previous or default wrappers will be passed.
