Using current binary build of Emacs 24.4 for Windows.
emacs-24.4-bin-i686-pc-mingw32
The use context is:
1 - Open a python source file
2 - M-x pdb  ;; run gud/pdb for the current .py
3 - step until a variable becomes defined/initialized
4 - hover the mouse over the variable name in the source
The errors:
Error running timer `tooltip-timeout': (wrong-type-argument markerp nil)
Command: next [4 times]
Error running timer `tooltip-timeout': (void-variable v) [2 times]

NOTES
- I have the tooltip.el tooltip-mode OFF/nil
- I have gud-tooltip-mode ON (obviously)
- If I start Emacs w/ --no-init, I can still reproduce the problem
- If I replace progmodes/gud.el , gud.elc with those from 24.3, the
errors do not occur

Other problems ensue on Windows when tooltip messages actually display
as tooltip windows, and I suspect maybe it is an HWND stealing problem,
but not sure and that's a different issue. I'm OK with the info being
printed to the "echo area"

I cannot reproduce this.  Does this happen for you in "emacs -Q"?

Can you show a backtrace from these errors?

Are you sure you are using gud.el, gdb-mi.el, and tooltip.el from
Emacs 24.4, not shadowing any of them with different versions?

I tested this with "M-x gdb" debugging emacs.exe, not "M-x pdb"
debugging a Python program (don't have a setup for the latter).  Do
you see the same problem with "M-x gdb"?  If not, perhaps PDB behaves
differently when it gets the request for values sent by Emacs, please
try to look into that.

A strange configuration, IMO, but I tried it is a well, and still
didn't see the problem.

I don't see any problems with tooltips on Windows, neither in GUD nor
elsewhere.  What problems do you see?

Btw, even if I turn tooltip-mode OFF, and verify it's off by hovering
the mouse above tool-bar buttons, GUD tooltips still show as balloon
help for me.  Not sure if this is a bug or a feature, but it doesn't
seem to cause any harm here.

Thanks.

This is above my pay grade.  Here's the Lisp backtrace, which I hope
will allow someone to pick up where I left off:

  Lisp Backtrace:
  "process-filter" (0x82d3e0)
  0x39e2a58 Lisp type 6
  "advice--add-function" (0x82d800)
  "if" (0x82da40)
  "if" (0x82db80)
  "let" (0x82dd20)
  "if" (0x82de60)
  "progn" (0x82df70)
  "if" (0x82e080)
  "let" (0x82e220)
  "progn" (0x82e330)
  "if" (0x82e440)
  "let" (0x82e5e0)
  "gud-tooltip-tips" (0x82e84c)
  "run-hook-with-args-until-success" (0x82e848)
  "tooltip-timeout" (0x82ec0c)
  "apply" (0x82ec08)
  "byte-code" (0x82ee8c)
  "timer-event-handler" (0x82f2cc)

(In case someone wonders how did we get to advice--add-function here:
it comes from add-function in gud-tooltip-tips.  I have no idea what
is the variable 'v' which triggers the error.)

Can you try the patch below?

Seems to fix the problem here, thanks.

Installed, along with a change in gv-ref to try and emit warnings when
bumping into similar situations.

Stefan,

Thanks for your attention to this.
I have to admit I wasn't sure what you were asking me to do per the 
patch, but it looked like it was just the addition of:

-*- lexical-binding:t -*-


so I tried replacing the first line of the gud.el that came with my 
build, byte-compiled it, and the problems are gone!

http://emacswiki.org/emacs/DynamicBindingVsLexicalBinding
and I see you (Stefan) referenced there.

Thanks again.
