 This happens because of bugs in Gtk+.  Gtk+ 2.10 seems to be OK.  See bug

+** Emacs compiled with Gtk+ crashes on startup on cygwin.

+A typical error message is
+  ***MEMORY-ERROR***: emacs[5172]: GSlice: failed to allocate 504 bytes 
+  (alignment: 512): Function not implemented
+
+Emacs supplies its own malloc, but glib (part of Gtk+) calls memalign and on
+cygwin that becomes the cygwin supplied memalign.  As malloc is not the
+cygwin malloc, the cygwin memalign always returns ENOSYS.  A fix for this
+problem would be welcome.
