            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: wine-bugs(a)winehq.org
          Reporter: alex(a)willner.ws

**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
> ...

*Any additional information:**

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

Assertion failed: !(size & host_page_mask)

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.

Same problem in 2026.

Surprised the breaking commit hasn't been reverted.

Worse, winecfg in Docker now hangs indefinitely with
scottyhardy/docker-wine:devel-10.4

This is frustrating. I didn't plan to spend all day troubleshooting wine, when
I simply want Wix Toolset in a Linux Docker container.

10.4 is the version for which this bug was originally reported.
Of course it's not fixed there.
The fix that supposedly fixed parts of it was merged in 10.10, so you should
try with a current version of wine.

Right, I already tried with a recent version of wine.

Tried both winehq-stable and and winehq-devel from the official wine repos.

Tried Debian and Ubuntu.

To clarify, the newer versions still have this qemu memory bug on Docker on
macOS hosts. That bug was never fixed.
