call burn_stack after the function invocation. This methods seems
to be the most portable way to zeroise the stack used. It does
only work on stack frame based machines but it is highly portable

the end of a function to zero does not work well because the
compiler will optimize them away - marking them as volatile would
be bad for performance.
