I tracked down an issue where an application was running into a sharing problem in WCMD_execute when it created redirects to the same file more than once. I originally hacked around this issue by changing the sharing mode for redirects, but I've now narrowed down the issue. I discovered that the file handle is not being closed when a command has completed and that this issue is caused by the "old handle" value being INVALID_HANDLE_VALUE: http://source.winehq.org/source/programs/cmd/wcmdmain.c#L1562 The "old handle" value is being set to this because of a call to GetStdHandle (you see, GetStdHandle(STD_OUTPUT_HANDLE) == INVALID_HANDLE_VALUE): http://source.winehq.org/source/programs/cmd/wcmdmain.c#L1399
So, my question is whether the call to GetStdHandle is important. If not then line 1399 can easily be simplified to: old_stdhandles[handle] = idx_stdhandles[handle]; Make this change resolves the sharing issue that I'm seeing, but if it is important to use GetStdHandle there then instead the "cleanup" code located near line 1562 needs to be more intelligent.
