Subject: bug#7145: elisp-code behaves differently after byte-compilation
Date: Sat, 02 Oct 2010 03:53:49 +0200 [thread overview]
Message-ID: <20101002015349.23590@gmx.net> (raw)
Hi,
I understand that byte-compiled code should do the same as the
uncompiled code (besides the macro-expansion problematic)
The following code however shows a case where this is not the case.
--- BEGIN CODE ---
(let ((fun (lambda () (let ((bar "foo")
(baz "foo"))
(eq bar baz)))))
(list (funcall (byte-compile fun))
(funcall fun)))
--- END CODE---
Evaluation this code (don't try to byte-compile it, because it is buggy ;-) ) results in:
--- BEGIN OUTPUT ---
(t nil)
--- END OUTPUT ---
which clearly means the byte compiation is somewhat broken. It seems
during compilation the two strings "foo" are treated as the same
string.
Regards
Markus
