I don't build Emacs.  The pretests I have _are_ those from the
FTP server by Phil Lord.  The one I mentioned is from 3/20.
The one on the site now is dated 3/21.  It does not seem that
multiple builds from different dates are available on that site -
the next one uploaded apparently just replaces the last one.

To be more clear: I have had some crashes using emacs -Q, but
generally when I try to make use of Emacs 25 it is with my setup,
which, among other things, uses a standalone minibuffer frame.
That is not common for Emacs users.  Likewise, the use of other
features, such as Icicles.

If this were something easily repeatable I would bisect my setup
to narrow down a repro recipe.  But it is not - there seems to
be no clear relation between the crash and something particular
that I do.

I really don't have the time to look into this now.  I have spent
some time in the past looking into it, but evidently not enough
to learn anything helpful about this.  I was hoping that the
emacs_backtrace.txt files would provide some help, but apparently
they are useless.

I apparently downloaded a version of GDB in 2015, but I don't
recall from where.  There is a gdb.exe, but if I double-click
that to run it I just get a message that guile.exe has stopped
working, plus these messages:

 Throw without catch before boot:
 Throw to key misc-error with args ("primitive-load-path"
 "Unable to find file ~S in load path" ("ice-9/boot-9") #f)Aborting.

 This application has requested the Runtime to terminate it in
 an unusual way.  Please contact the application's support team
 for more information.

If you send me some instructions that tell me (1) where to get
a Windows 64-bit (or 32-bit?) binary GDB, (2) how to run Emacs
under it, to obtain the info you need, I will try to take a
look when I get some time.  Sorry for the trouble.
