Bug ID: 38785
           Summary: Client Wait Sync Timeout
           Product: Wine
           Version: 1.7.45
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: [e-mail]
          Reporter: [e-mail]

Testing Chessmaster 10 Demo I got a crash and trace it in log having a message
---
glClientWaitSync returned 0x911b
---

This is GL_TIMEOUT_EXPIRED_APPLE and there is a comment related to this
----
        /* Apple seems to be into arbitrary limits, and timeouts larger than
         * 0xfffffffffffffbff immediately return GL_TIMEOUT_EXPIRED. We don't
         * really care and can live with waiting a few μs less. (OS X 10.7.4).
*/

I know how you like Apple so I decided to add here
----
        switch (gl_ret)
        {
            case GL_ALREADY_SIGNALED:
            case GL_CONDITION_SATISFIED:
                ret = WINED3D_EVENT_QUERY_OK;
                break;
            /* here my addition */
+            case GL_TIMEOUT_EXPIRED_APPLE:
+                ret = WINED3D_EVENT_QUERY_NOT_STARTED;
+                break;
---------
and voila! Chessmaster works and no more crashes.

So there is my question. Why default return WINED3D_EVENT_QUERY_ERROR causes
crash?
