I have the vaguest memory of watching a movie when I was a kid. The only scene I remember is, a man is in the woods and draws a circle in the dirt to protect himself from a witch or a gypsy. He is protected as long as he remains in that circle.
I wish I remembered more.
Apprentice to Murder (1988)?

I saw it in the early 80s on tv. So it would have probably been from the late 70s.
“Shadow of the Hawk” (1976)?
There is a scene with a man in the center of a circle at 2:08 of the trailer posted below.
