A simple console application that outputs Hello macOS

Wine 6.1 (from HomeBrew, gcenx-wine-devel), macOS 12 Monterey Beta 12

Hello,

Wine used to work fine on my machine running macOS 11 Big Sur.
I migrated it to macOS 12 Monterey Beta 12, and now it works for some programs
but not for all of them.
I have noticed this warning:
  preloader: Warning: failed to reserve range 0000000000110000-0000000068000000
and indeed Wine cannot load programs with base address in this range.
If I just change the base address from 0x400000 to 0x80000000 (above
0x68000000), it works fine.

I think that the Wine preloader should use the relocation section and relocate
the executable if it fails to load it at its preferred address.

I attach hellomacos.exe, a simple Delphi program build with this code:
program hellomacos;

{$APPTYPE CONSOLE}

{$R *.res}

begin
  Writeln (Output, 'Hello macOS');
end.

Regards,

Michel Terrisse
