FWIW, this crash makes this build unusable for me.
There is no such crash in a build from 2010-07-19.

I still get this crash systematically in the latest build from yesterday.

GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600) of 2010-08-16 on 3249CTO

It crashes systematically with the same simple recipe in every build I have
since 7/19 - that means builds of 8/02, 8/09, and 8/16.

Emacs 24 is now unusable for me, so I hope this will be fixed soon.

I cannot get the packages you cite as needed to reproduce the problem;
the URL seems to be invalid.

Also, is it really a crash, or does Emacs just enters the Lisp
debugger?

The URL is perfectly valid, though it might have been split across two lines in
the mail so that you need to sew it together again.  Here it is again:

http://www.emacswiki.org/cgi-bin/wiki?action=index;match=%5C.(el%7Ctar)(%5C.gz)%
3F%24

This is simply the Elisp area of Emacs Wiki.
Here is another URL to the Elisp area, unsorted:
http://www.emacswiki.org/emacs/ElispArea

The first URL I posted is what you get by clicking the link under 1.
Downloading, 1. Elisp Files - Alphabetical.

It is really a crash. I showed as much of the Lisp debugger as I was able to see
before Emacs crashed.

I have not looked at this bug at all, but I wonder if it is related to
the crahes I reported before. I think the patch I sent never got
installed, but I am not sure.

I cannot reproduce this, sorry.  I have 2 builds, one from Aug 8, the
other one from Aug 14, and none of them crashes with your recipe.

One question, to be sure I did what you did: How did you invoke this
line:

  (global-set-key [(control ?z)] 'iconify/map-frame)

I pasted it to *scratch* and then typed C-j after the right paren to
evaluate it.

Yes, doing that way reproduces the crash.

But you must also do the following steps to get the crash.
Sorry that I forgot to mention them:

3. C-z
4. C-z

Step 3 thumbifies the frame. Step 4 should dethumbify it. C-z is a toggle to
replace iconify/map by thumbify/dethumbify.  Step 4 crashes Emacs.

Compare with a build of 7/19 or prior, to see the expected behavior.

Thx.

C-z did the trick.  The problem was caused by Jan's changes from July
29 to support tool bar positioning in GTK builds: this change added a
new frame parameter tool-bar-position, but the array of w32 handlers
for frame parameters was not extended to add a slot for this
parameter.

This bug is now fixed (revno 101110).
