Calling a undefined function with 3 arguments leads to a CCL::INVALID-MEMORY-ACCESS error. It doesn't seem like that is supposed to happen; I would expect a CCL::UNDEFINED-FUNCTION-CALL error instead:

If your ccl-init.lisp is actually a symlink to a file elsewhere and you meta-dot on a definition in that file, Hemlock opens a window to the symlink rather than the actual file. (It shows a small arrow in the titlebar icon of the window). Edits to this "file" can be made but CCL throws an error when you try to save them.
