Start Emacs with emacs -Q. Go to grep.el, l.916 in function regrep. Set
breakpoint with `C-u C-M-x'. Run `M-x rgrep'. Press `i' to step into the
function. The debugger pops up with the following backtrace:

The error appears because you tried to instrument a built-in function.
I improved the error message to make it more obvious.
