Bug ID: 54757
           Summary: d3d11:d3d11 - test_resource_access() sometimes
                    triggers a wined3d assertion
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]

d3d11:d3d11 - test_resource_access() sometimes triggers a wined3d assertion:

d3d11.c:15552: Test marked todo: Feature level 0xb100: Got hr 0 for WRITE.
Assertion failed: bo->b.map_ptr, file ../wine/dlls/wined3d/context_gl.c, line
3049
d3d11:d3d11:06e8 done (3) in 9s 15479B

See https://test.winehq.org/data/patterns.html#d3d11:d3d11

The assertion always happens after the same trace so it is likely caused by
this test_resource_access() line:

15552      check_resource_cpu_access(context, resource,
15553               texture_desc.Usage, texture_desc.BindFlags,
texture_desc.CPUAccessFlags);
15554      ID3D11Resource_Release(resource);

And the assertion happens in wined3d_context_gl_unmap_bo_address():

3049    assert(bo->b.map_ptr);

The oldest known instance happened on 2023-02-23 and there has been about one
further failure per week since, all in the pure 32-bit tests on the debian11
TestBot VM.

--- Comment #1 from Zeb Figura  ---
My guess is that it fails to map, presumably by virtue of running out of
address space. Do we have stderr from any of the relevant runs?

--- Comment #2 from François Gouget  ---
Yes, here for instance:
https://testbot.winehq.org/JobDetails.pl?Key=131163&f103=task.log#k103

I think this confirms the out-of-memory issue. The next question is why does
this happen? And is an assert the right way to handle this?
