I have beend debuging the crash and problem seems to be this (at leas in d3d8
test case)

Wine frequantly disables VERTEX_PROGRAM_ARB in shader_select function. In the
test that crash happens DrawPrimitiveUP is called with vertex shader enabled
but wine never tells GL to enable vertex prgorams before glDrawArrays is
called. Now driver tries to handle drawing code but it thinks fixed function
pipeline should be used for vertex processing because vertex program isn't
enabled.
assertion failure happens in code that tries to upload fixed function data to
card but wine haven't provided correct data for that.


If I enable VERTEX_PROGRAM_ARB in IWineD3DDeviceImpl_CreateVertexShader all
test case are run but I get 3 failures. So problem is that wine doesn't
correctly call shader_select before trying to render the scene.
