Bug ID: 52157
           Summary: ntdll:wow64 fails on 64-bit Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

ntdll:wow64 fails on 64-bit Wine:

wow64.c:329: Test failed: debugging failed
wow64.c:332: Test failed: BeingDebugged is 0
wow64.c:337: Test failed: BeingDebugged is 0

https://test.winehq.org/data/patterns.html#ntdll:wow64

The timeout only happens on WoW64 wineprefixes but impacts both real machines
(cw-gtx560, cw-rx460) and VMs (notably the TestBot's debiant2 VM).

A bisect shows that this started with the commit below:

commit a041075cd2c26874757e0b6e1449c23c1326241c
Author: Alexandre Julliard 
Date:   Thu Dec 2 09:59:49 2021 +0100

makefiles: Support per-platform values for EXTRADLLFLAGS.

However the current thought is that the commit only revealed a preexisting bug
by changing the ntdll base address.
