Hm. It currently has a bunch of known limitations, and the debug output probably isn't helpful to anyone other than me at the moment, but that test case works on my Maverick (Ubuntu 10.10) and Lucid (10.04) systems, so I'm not sure why it's failing for you. If you'd like me to take a look, the most helpful thing you could get me would be to install strace, and then run strace -o /tmp/reptyr.strace ~/src/reptyr/reptyr PID and then send me the contents of /tmp/reptyr.strace Thanks!
