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

Same problem with Wine 6.13.
Can you reproduce the problem?
I just asked my company to order a CrossOver Licence, I will test with
CrossOver too (and I am almost sure that CrossOver won't work either).

I found this page at CrossOver that explains things :
https://www.codeweavers.com/support/forums/general/?t=27;msg=240166#c3
with this comment from Jeremy Newman:
"Monterey changed how thread 0's stack works. This affects the Wine preloader
when it tries to reserve some memory in that region. Our devs understand the
issue and already have planned fixes."

Good news, this is fixed in macOS Monterey Beta 6 Update (21A5506j).
You can close this ticket.
