Bug ID: 52184
           Summary: Initial breakpoint absent when debugging under
                    WinDbg/CDB (build 22000.1)
           Product: Wine
           Version: 6.23
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When debugging with WinDbg or CDB (build 22000.1), the initial breakpoint
before the program entry point is not hit at all.

This appears to be because DbgEng creates the debug port object with limited
access permissions, causing NtQueryInformationProcess/ProcessDebugPort to fail
with STATUS_ACCESS_DENIED.  This leads to Wine's process_breakpoint() function
(called by LdrInitializeThunk) failing to detect that the current process is
being debugged, and the initial breakpoint is skipped.
