           Summary: GC emits HLT when GetThreadContext fails after
                    CreateRemoteThread.
           Product: D
           Version: 2.002
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: wqeqweuqy at hotmail.com


If an external process trys to CreateRemoteThread the current process (to
inject a DLL in this case) the gcx stack scanning code fails in
GetThreadContext(). 

GetLastError() returns ERROR_GEN_FAILURE and the code hard exists via a HLT
instruction.

Seems a few anti virus/spyware utilities use this injection method, so its
likely to be a problem.
