Hi All, I've built the latest libtorrent / rtorrent, packaged it and tested it on WinXP x86 with no issues. I then attempted to test on Win7 x64 and it's crashing constantly. I've disabled Windows Defender and uninstalled my antivirus software, done a rebaseall, and nothing seems to help. I'd appreciate any pointers on what to try next, as I'm at a bit of a loss. I've attached by cygcheck.out and would be more than happy to provide an strace if that would be useful. Thank you, Chris -- Chris Sutcliffe http://emergedesktop.org http://www.google.com/profiles/ir0nh34d
