Hi,
I use latest systemtap to probe multiple function, and system will
crash if register_kprobe for one function fails. I checked systemtap
source code, in function _stp_handle_start(), if probe_start( )
return < 0, _stp_exit_called will be equal 1. So that _stp_kill_time
will never be called in function _stp_cleanup_and_exit(), but
_stp_init_time is ever called.

This seems to be the cause of bug 3215: http://sources.redhat.com/bugzilla/show_bug.cgi?id=3215

Martin just checked in a fix, so let us know if you still see problems.
