Zeus: Master of Olympus triggers an access violation when exiting through the
main menu in Wine 11.20. This does not occur with Wine 11.19.

The game window closes without displaying a Wine crash dialog, but the
following error appears in the terminal:
> > err:seh:send_debug_event Exception c0000005 in system thread at 0x74c0860a2bdc

I have reproduced this with both the GOG release and the freely available demo,
using both new WoW64 and legacy shared WoW64 builds.

To reproduce:
1. Install the GOG release or the demo.
2. Start the game and wait for the main menu.
3. Click Quit.
4. Observe the system-thread access violation in the terminal.

The game starts and reaches the main menu normally. I have not observed any
gameplay problems during brief testing, but I have not tested extended
gameplay. Entering a game is not necessary to reproduce the exit failure.

Git bisect identified the first bad commit as:
commit 1cae1f531bf5762c6009cd06975075328609c2f9
ntdll: Merge the reserved areas and free ranges arrays.

The commit reverts cleanly, and reverting it fixes the exit failure.

Possibly related: bug #60534

Demo installation note:
The demo installation can take a long time to start and may print a Win16Mutex
timeout warning, but it eventually installs successfully.
