--- Comment #2 from David Smith <dsmith at redhat dot com> ---
In theory, any stap script that calls any of the gettimeofday_*() functions
should cause this bug, but the following script doesn't show this bug:

# stap -ve 'probe begin { printf("%d\n", gettimeofday_s()) }'

Calling any of the gettimeofday_*() functions causes _stp_init_time() to be
called.
