            Bug ID: 52909
           Summary: rpcrt4:ndr_marshall crashes on the latest Windows 21H1
                    and 21H2
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: rpc
          Assignee: wine-bugs at winehq.org

rpcrt4:ndr_marshall crashes on the latest Windows 21H1 and 21H2.

ndr_marshall.c:165: this is the last test seen before the exception
0770:ndr_marshall: unhandled exception 000006f7 at 00007FFCF0874F69

However the crash is not detected as such so the patterns page reports it as a
failure:
https://test.winehq.org/data/patterns.html#rpcrt4:ndr_marshall

I don't know what this 0x000006f7 exception is.

When w10pro64 had the updates up to 2021-10-21 this test was not crashing. The
crashes started happening when w1064 and w10pro64 were updated on 2022-04-24.
So the crash is probably caused by one of the Windows updates in that interval.
If necessary I can dig into the Windows update history to try and find
something related.
