Okay, my attachments screwed up, so check: <URL:http://green.homeunix.org/~green/sel_crash_2.txt> <URL:http://green.homeunix.org/~green/sel_crash_2_uma.txt> Note that the first fd (pipe) returned with revents set, and was removed from the select queue. In the select queue there are four valid selinfos that correspond exactly with all the sockets being selected on, but then the last invalid one appears from what I can tell to be from one of these objects; it couldn't be in the generic '256' bucket if it wasn't a malloc, right?
