Re: [PATCH v2 0/1] MR9218: ntdll: Stop unwinding on access violation.

[Dylan Donnell (＠dy-tea)]

Yes I have a test that crashes under wine but not windows, on windows it returns 0 so I replicated that in my mr:
```c
#include <windows.h>
#include <stdio.h>

int main() {
    void *retaddr = __builtin_extract_return_addr(__builtin_return_address(0));

    DWORD64 imagebase;
    UNWIND_HISTORY_TABLE table;
    RUNTIME_FUNCTION *rf = RtlLookupFunctionEntry((DWORD64)retaddr, &imagebase, &table);

    DWORD old;
    VirtualProtect(rf, 0x100, PAGE_READWRITE, &old);

    rf->UnwindData = 0x12345678;

    VirtualProtect(rf, 0x100, old, &old);

    void *bt[100];
    RtlCaptureStackBackTrace(0, 100, bt, NULL);

    return 0;
}
```
