Bug ID: 53835
           Summary: cefclient.exe crash on CHECK_EQ(PAGE_READWRITE,
                    old_protection);
           Product: Wine
           Version: 7.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]

void OS::SetDataReadOnly(void* address, size_t size) {
  DCHECK_EQ(0, reinterpret_cast<uintptr_t>(address) % CommitPageSize());
  DCHECK_EQ(0, size % CommitPageSize());
  unsigned long old_protection;
  CHECK(VirtualProtect(address, size, PAGE_READONLY, &old_protection));
  CHECK_EQ(PAGE_READWRITE, old_protection);
}

the last line assume old_protection==PAGE_READWRITE, but it is PAGE_WRITECOPY
in wine, CHECK_EQ failed will raise a int3 break crash.

you can download cefclient.exe from
https://cef-builds.spotifycdn.com/cef_binary_106.1.1%2Bg5891c70%2Bchromium-1...
, and run it by "wine64 cefclient.exe --no-sandbox --use-gl=angle
--use-angle=swiftshader --in-process-gpu" to reproduce the problem.
