Well I further found out that you have to actually (byte-compile-file)
the above code in order for the bug to show up; compiling via
(compile-defun) seems to work OK;
I can't reproduce this. Could you detail the *exact* steps you took,
starting with `emacs -Q'? Your description is too vague.
1) Start `emacs -Q'
2) Load the file bug.el into a buffer via the menu
3) <M-x> byte-compile-file
4) <M-x> load-file bug.elc
5) <C-x b> *scratch*
6) (foo) *** emacs crashes or foo returns some odd number ***
(disassemble 'foo) looks like this (done between point 5 and 6)
byte code for foo:
args: nil
0 constant (message "Hello World!")
1 constant (out-of-range 2)
2 catch
3 dup
4 varbind :eof
5 constant (message "Hello World!")
6 eq
7 not
8 goto-if-nil-else-pop 1
11 varref :eof
12:1 unbind 1
13 return
I attached the file I used for testing this and also it's byte compilation
bug.elc
Description: Binary data
(defmacro bar (&rest body)
(let ((v (make-symbol ""))) ; Crashes with "" as name.
`(let ((,v (catch :eof
,@body)))
(when (not (eq ,v :eof))
,v))))
(defun foo ()
(bar (message "Hello World!")))
