This is something that Wine cannot accurately emulate. On Linux, only root may bind to ports < 1024; on Windows, anyone may do so. So this behaviour would be fine on real Windows, but is not OK under Wine. If libdbus is calling (pseudocode) bind(address=127.0.0.1, port=0) then I would expect the kernel (or the part of Wine that emulates the Windows kernel) to give it a high port number. That's what happens on native Linux. Was this before we fixed the incorrect endianness thing? If so, then it's probably fixed now. I suspect that what happened is: * we call bind() with port 0 * the kernel gives us port 48129 (0xbc01) * we store the byteswapped port number 444 (0x01bc) and do the goto * we call bind() with the incorrect port 444 * the kernel says no, because 444 < 1024 If it works for you now (manual-tcp worked for me while I was preparing 1.9.8) then we can close this as a dup of Bug #87999.

Works for me too, thanks for investigation. *** This bug has been marked as a duplicate of bug 87999 *** |
