Hi i can confirm there is a crash. seems like a problem in NtQueryObject.

002f:Call msvcrt._get_osfhandle(00000001) ret=005db4b9
002f:Ret  msvcrt._get_osfhandle() retval=000000b4 ret=005db4b9

002f:Ret  ntdll.NtQueryObject() retval=00000000 ret=005db512

002f:trace:seh:NtRaiseException  info[1]=0000000000000000


I might be off  (little late) but msdn suggests enumeration for the
OBJECT_INFORMATION_CLASS is wrong in wintern.h.
(https://docs.microsoft.com/en-us/windows/desktop/api/winternl/nf-winternl-ntqueryobject)

msdn suggests
ObjectBasicInformation =0
ObjectTypeInformation =1

and wintern.h says ObjectTypeInformation =2 or am I missing something/see it
wrong?



The following hack makes crash dissapear:

diff --git a/include/winternl.h b/include/winternl.h
index 46dac7e481..9ff5358b6e 100644
--- a/include/winternl.h
+++ b/include/winternl.h
@@ -824,8 +824,8 @@ typedef enum _KEY_VALUE_INFORMATION_CLASS {

 typedef enum _OBJECT_INFORMATION_CLASS {
     ObjectBasicInformation,
-    ObjectNameInformation,
     ObjectTypeInformation,
+    ObjectNameInformation,
     ObjectAllInformation,
     ObjectDataInformation
 } OBJECT_INFORMATION_CLASS, *POBJECT_INFORMATION_CLASS;



I did 
/tmp/wine-git-bug/.build$ wine ../tools/bin/cmake.exe .. -G "Unix Makefiles"

With the hack/patch:
Is this expected output?
