      Using the attached example, pass a network share path as arguments:

      d:\dev\projects\cmdargs_5>release\cmdargs.exe \\server\path
5.2.1
0 release\cmdargs.exe
1 \\server\path
("release\cmdargs.exe", "\server\path")

      whereas in Qt 4:

      d:\dev\projects\cmdargs_4>release\cmdargs.exe \\server\path
4.8.6
0 release\cmdargs.exe
1 \\server\path
("release\cmdargs.exe", "\\server\path")

      "
      " is changed to "\" in the debug output of QCoreApplication::arguments(). It seems to perform some backslash-escaping which it clearly shouldn't. Quoting in double-quotes does not help (note it is possible for example to start

      explorer \\server\path

      , so, the Windows shell clearly does not do backslash-escaping). This is pretty serious as you cannot pass cmd line arguments of that type to any application.
