http://bugs.winehq.org/show_bug.cgi?id=60204 --- Comment #2 from Alisa Sireneva <me@purplesyringa.moe> --- Created attachment 81890 --> http://bugs.winehq.org/attachment.cgi?id=81890 Binary reproducer I don't know any well-known program using this -- some async frameworks use AcceptEx, but at least Rust's tokio seems to have dropped it, and I don't think it ever supported it in combination with AF_UNIX. I want to submit a PR to Rust to use it by default, but that hasn't happened either. But I can provide a test program I'm working on that uncovered this. It tests IPC for https://github.com/purplesyringa/crossmist; you can find the relevant code using AcceptEx at [1], the CI job that passes on native Windows at [2], the Wine failure at [3], and the CI-built test at [4] (you want tmp.rOduF6V1VK). If that's not enough, I can provide a C reproducer in a bit if necessary. [1]: https://github.com/purplesyringa/crossmist/blob/7130fbe56e5e4272fdbad8499512...
