I'm running 64-bit Windows 7 with the 2012-09-17 Cygwin snapshot.  [I 
got similar results on a different machine with the 2012-10-12 
snapshot.]  The development packages I've installed are shown in the 
attached devel.txt file.  I'm building emacs with the command

./configure --with-w32 CFLAGS='-g -O0' && make

The Emacs abort dialogue box pops up when the build gets to this point:

At this point I attached gdb.  The session didn't provide any 
information that I can see, but I'm attaching a log (gdb.txt).

My build was based on the trunk as of bzr revision 110552.

FWIW, here's a stack trace from an earlier build attempt in which I 
didn't attach gdb and just let emacs abort:
