--- Comment #4 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to Henri Verbeet from comment #3)
Is there any chance this has a kernel dependency? It succeeds for me on a box with a 3.10 kernel, but fails on a different one with a 3.12 kernel, although that's hardly the only difference between those two setups. And e.g. http://test.winehq.org/data/ecd24b5a874ead368c8f6e9d6981bb0e02472f9d/ linux_Yuanchen/kernel32:pipe.html is on a 3.2 kernel.
Good point, pipe.ok fails for me with 3.13.6, but succeeds with 3.10.33. This is a 64-bit system, with 32-bit wine build.
