Bug ID: 58084
           Summary: Commit d813ffc3 (ntdll: Align virtual memory
                    allocations to the host page size) breaks Wine in a
                    Rosetta emulated Docker environment
           Product: Wine
           Version: 10.5
          Hardware: arm
                OS: MacOS
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

**Version:** 10.5 and 10.4

**Steps that will reproduce the problem:**

On an arm64 M2 run macOS 15.4 (24E248) and execute with Docker version 28.0.4
(b8034c0):
docker run --platform linux/amd64 --rm scottyhardy/docker-wine:devel-10.4 sh -c
'wine --version && winecfg'

**What is the expected result:**
> % docker run --platform linux/amd64  --rm scottyhardy/docker-wine:devel-10.5 sh -c 'wine --version && winecfg'
> wine-10.5
> wine: created the configuration directory
> ...

**What happens instead:**
> wine-10.5
> wine: dlls/ntdll/unix/virtual.c:253: anon_mmap_fixed: Assertion `!((UINT_PTR)start & host_page_mask)' failed.
> qemu: uncaught target signal 6 (Aborted) - core dumped
> Aborted

**Possible workaround:**

Downgrade to Wine 10.4:
> % docker run --platform linux/amd64  --rm scottyhardy/docker-wine:devel-10.4 sh -c 'wine --version && winecfg'
> wine-10.4
> wine: created the configuration directory
> ...

i have found the same issue on aarch64-linux-musl

Assertion failed: !(size & host_page_mask)
(/home/cqwrteur/toolchains_build/wine/dlls/ntdll/unix/virtual.c:
alloc_virtual_heap: 3421)
Aborted

So according to my calculations this is what happens on a 4k pagesize system
with 38 bits address space:

virtual_init:
pages_vprot_size = ((size_t)host_addr_space_limit /* 0x7fffff0000 */ >>
page_shift /* 12 */ >> pages_vprot_shift /* 20 */) + 1; /* = 0x80 */
size = 2 * view_block_size + pages_vprot_size * sizeof(*pages_vprot); /* =
0x200400 */

alloc_virtual_heap:
assert( !(size & host_page_mask) ); /* 0x200400 & 0xfff */ //->boom

396207f4f1ad8903876a31cecbf5756f321295a9 fixed this, but not sure about the
similar problem on mac. Somehow this bug is about two different issues.

It seems
https://gitlab.winehq.org/wine/wine/-/commit/396207f4f1ad8903876a31cecbf5756...
did not fix the problem on mac:
> % docker run --platform linux/amd64  --rm scottyhardy/docker-wine:devel-10.7 sh -c 'wine --version && winecfg'
> wine-10.7
> wine: dlls/ntdll/unix/virtual.c:267: anon_mmap_fixed: Assertion `!((UINT_PTR)start & host_page_mask)' failed.
