Hello,
I've built emacs from git sources on a recent cygwin this morning and
when I try and run it, I get the following error on startup before it
crashes:
***MEMORY-ERROR***: [7588]: GSlice: failed to allocate 504 bytes
(alignment: 512): Function not implemented
Fatal error 6: Abortedaborted (core dumped)
Here's a gdb run with a not very useful looking backtrace:

This used to be a problem with the gtk build, for which the following
workaround was put into emacs.c long ago:
#if defined (USE_GTK) && defined (G_SLICE_ALWAYS_MALLOC)
/* This is used by the Cygwin build. */
setenv ("G_SLICE", "always-malloc", 1);
#endif

My guess is that Cygwin doesn't support building with x-toolkit=athena
(or else you don't have the appropriate devel packages installed). The
build probably then reverted to the default gtk, but USE_GTK wasn't
defined, so the code above didn't get invoked. I'm guessing, because I
can't tell anything from the config.log fragment that you attached, and
I don't have time right now to dig into the code or to try a build with
x-toolkit=athena myself.

I see the problem. (And the guess in my previous email was wrong.)
The workaround above was intended to solve a problem on Cygwin whenever
the emacs build depended on Glib. When I provided that workaround, I
thought this only happened in a GTK build. But I see now that there are
other things that can cause emacs to depend on Glib, even in a Lucid
build. This happens in both the trunk and the emacs-24 branch.
The following patch fixes it:
=== modified file 'src/emacs.c'
--- src/emacs.c 2012-10-31 17:27:29 +0000
+++ src/emacs.c 2012-11-19 20:50:37 +0000

setenv ("G_SLICE", "always-malloc", 1);
#endif
Stefan, is it OK to apply this to the emacs-24 branch? The bug is not a
regression, but I think the patch is clearly safe. And it affects only
the Cygwin build.

That patch worked for me, and the build no-longer crashes on
startup. Thanks.

Yes, go ahead, please install it on the emacs-24 branch rather than on
the trunk.

Could you test it with the `emacs-24' branch? That's where the
testing&bugfixing is focused right now,
