Bug ID: 51668
           Summary: mscoree tests fail, .NET executables usually fail to
                    run
           Product: Wine
           Version: 6.15
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal

The mscoree tests fail since the following commit:

ntdll: Always send a Wow context to the server for Wow64 processes.

Attempting to run a .NET exe often hangs after printing:
0114:err:module:relocate_ntdll ntdll could not be mapped at preferred address
(0x410000), expect trouble

I haven't quite figured out the pattern. Using "wine64" instead of "wine"
sometimes helps. I've noticed that run-tests.exe from the wine-mono tests will
work when called with "wine64" but it'll then fail to call any 64-bit
executables.
