So the fix there has to be done in cygwin and not us - presumably they have either already fixed it, or will fix it in order to get general compatibility with the new ASLR versions. Mingw is a different story. But some googling indicates that mingw disables ASLR by default. You need to specify --dynamicbase if you want to to be dynamic, which we don't. (Being mingw I've not managed to find any actual docs, but for example http://lists.cypherpunks.ca/pipermail/otr-dev/2012-August/001373.html seems to indicate it has to be enabled). -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
