Without kernel debuginfo installed, observe the following:
# stap -vvv -e 'probe process("/bin/program_that_does_not_exist").death { }'

Even if this shouldn't compile, a better error message (or any for that matter)
should be emitted.

Chances are the problem is in the code associated with
collecting symbol table data. I'm already working on the
area, and will probably end up borrowing code from jkenisto's
dwarfless branch (looking for System.map?) order to do
the deed.
