--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
The problem is that in the end probe systemtap doesn't know with which user
space process the ustack backtrace addresses belong to (the process might even
no longer exist).

If you want to save the actual stack/symbols and use/print them in an end probe
you might want to use sprint_ustack or sprint_usyms.
