Thanks for the confirmation. It looks like I am allowed to migrate the machines to a 3GB VM, thus circumventing the heap collision with DLL. Meanwhile I've looked at some problems that typically happen when loading emacs-x11 and it turns out that this loads a number of Windows DLL related to the display drivers and some others related to networking to low addresses. The only way I see to get around that is to try to enable ASLR, so what's the latest on doing that with Cygwin DLL? As far as I understand we should then rebase from 0x50000000 down since the range above is used by ASLR for any DLL that we still need top load to fixed addresses?
