--- Comment #1 from Giovanni Mascellani <gmascellani at codeweavers.com> ---
This seems to be an unhandled memory allocation failure:

01f8:err:d3d:wined3d_debug_callback 001AFFA8: "GL_OUT_OF_MEMORY in
glBufferStorage".
01f8:err:d3d:wined3d_debug_callback 001AFFA8: "GL_INVALID_VALUE in
glMapBufferRange(offset 0 + length 67108864 > buffer_size 0)".
01f8:err:d3d:wined3d_allocator_chunk_gl_map Failed to map chunk memory.
01f8:err:d3d:wined3d_bo_gl_map Failed to map chunk.
01f8:err:d3d:wined3d_context_gl_map_bo_address Failed to map bo.
wine: Unhandled page fault on write access to 00000000 at address 70BAFD94
(thread 01f8), starting debugger...

BTW, on the testbot running with +d3d gives:

00f8:trace:d3d:wined3d_adapter_init_gl_caps GL_RENDERER: "llvmpipe (LLVM
11.0.1, 256 bits)".
00f8:trace:d3d:wined3d_adapter_init_gl_caps GL_VENDOR: "Mesa/X.org".
00f8:trace:d3d:wined3d_adapter_init_gl_caps GL_VERSION: "4.5 (Core Profile)
Mesa 20.3.5".

While on my computer (using "LIBGL_ALWAYS_SOFTWARE=1 GALLIUM_DRIVER=llvmpipe"
to force llvmpipe) I get:

0024:trace:d3d:4P:714CB0E3:ine/dlls/wined3d/adapter_gl.c:3413:wined3d_adapter_init_gl_caps
GL_RENDERER: "llvmpipe (LLVM 14.0.4, 256 bits)".
0024:trace:d3d:4P:714CB0E3:ine/dlls/wined3d/adapter_gl.c:3421:wined3d_adapter_init_gl_caps
GL_VENDOR: "Mesa/X.org".
0024:trace:d3d:4P:714CB0E3:ine/dlls/wined3d/adapter_gl.c:3430:wined3d_adapter_init_gl_caps
GL_VERSION: "4.5 (Core Profile) Mesa 22.0.5".

So it might be a bug that was fixed between Mesa 20.3.5 and Mesa 22.0.5. In
theory Wine should gracefully handle the failed allocation anyway.
