Insert this into a .el file and load it in using emacs -Q:
(let ((page-name "the page"))
(let ((regexp
;; (concat "[[" page-name "]]")
(rx "[[" (eval page-name) "]]" )))
regexp
))
Move point somewhere inside that expression and type C-M-x which is
bound to (eval-defun EDEBUG-IT). Get the error:
Debugger entered--Lisp error: (void-variable page-name)
eval(page-name)
rx-eval((eval page-name))
rx-form((eval page-name) :)
#[(x) "\301\b\302\"\207" [x rx-form :] 3]((eval page-name))

eval-defun-2()
eval-defun(nil)
call-interactively(eval-defun nil nil)
command-execute(eval-defun)
But if you evaluate that buffer using M-x eval-buffer you get:
Eager macro-expansion failure: (void-variable page-name)

rx is a macro so it doesn't see runtime bindings, using
let-when-compile (new in Emacs 25) works:
(let-when-compile ((page-name "the page"))
(rx "[[" (eval page-name) "]]"))
Not sure if the plain let case can/should be fixed.

Ok thanks Noam. Then I conclude this isn't a bug per se.

Since rx is a macro it cannot refer to runtime values. You need to use
rx-to-string to construct the regexp at run time. Or just use concat as
in the comment.
Andreas.
