Bug ID: 50937
           Summary: mscoree tests fail with "Compilation failed"
           Product: Wine
           Version: 6.5
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

mscoree:comtest and mscoree:mscoree tests fail trying to call csc.exe.

The comtest failures look like this:

comtest.c:102: Test failed: Compilation failed
comtest.c:105: Test failed: Moving temporary file failed
comtest.c:377: 2 failures in child process

And the mscoree failures:

mscoree.c:591: Test failed: Compilation failed
mscoree.c:591: Test failed: Compilation failed

It seems the csc.exe process dies very early on, such that it doesn't show up
in a +relay log at all, but it is in a +server log.

Bisect result:
