           Summary: Cygwin apps can't start up, fail creating a mailslot
           Product: Wine
           Version: CVS/GIT
          Platform: Other
               URL: http://cygwin.com
        OS/Version: other
            Status: NEW
          Keywords: download, Installer
          Severity: normal
          Priority: P2
         Component: ntdll
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


Installing Cygwin with all defaults works fine up until it
tries to run the postinstall bash scripts.
When it fails, kill it, then just try to run bash; you'll
get the same error.  Here's a log; it shows a problem creating a
mailslot immediately before the crash.  Our current mailslot conformance
test doesn't test quite this kind of path, fwiw.
