I don't know if this is the cause of the failure, but the test still has a
race condition. If get() calls get_elements(), which returns false, and then
the writer pushes the last elements and sets running to false, get() will
then return.

I suppose it needs to be something along the lines of:

void get(void)
    while( running )

    while( get_elements() );

or equivalent.
