I just checked out and recompiled Emacs from bzr and tested. I'm still
seeing the same bug as before. Steps to reproduce:

1. Open the attached elisp file

2. Instrument `test' for edebug: "C-u C-M-x"

3. Evaluate `test': "M-: (test 3)"

4. Evaluate lexical variable from within edebug: "M-: arg <ret>"
-> backtrace buffer with "Debugger entered--Lisp error: (void-variable arg)"

3'. Create conditional breakpoint in `test': "C-x X x (null arg) <ret>"

4'. Evaluate `test': "M-: (test 3)"
-> message "Symbol's value as variable is void: arg"


Best,
Toby
