https://bugs.winehq.org/show_bug.cgi?id=55054 --- Comment #9 from Fabian Maurer <dark.shadow4(a)web.de> --- Created attachment 75560 --> https://bugs.winehq.org/attachment.cgi?id=75560 wineserver.log Attaching commented log from wineserver when the issue appears. As you see we have two socket entries, and when processing the second entry the first entry is altered, and poll_socket is left with flags != 0 which should never happen. This will cause the assert later during async_poll_timeout. Reason is the event we get in sock_poll_event when processing the second entry.
