            Bug ID: 49666
           Summary: Red Dead Redemption 2 requires HEAP flags offset to
                    match Windows
           Product: Wine
           Version: 5.14
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs at winehq.org
          Reporter: bshanks at codeweavers.com
      Distribution: ---

Red Dead Redemption 2 gets ProcessHeap from the PEB, and directly accesses the
'flags' and 'force_flags' fields of the HEAP structure.

Those fields need to be at the same offset as they are on WinVista through
current Win10, 0x40/0x70.
Wine currently pads the struct so 'flags' is in the correct place (0xC) vs.
WinNT/2000/XP
