<pre>It seems that z buffer is not optional to pp_run looking at other codes
but it is not checked in osmesa_st_framebuffer_flush_front().
It crashes if zsbuf is NULL with pp_jimenezmlaa. With pp_nored it doesn't
crash,
but if pipe_sampler_view.reference is not the first member in
struct pipe_sampler_view, it would crash in pipe_sampler_view_reference at
<span class="quote">> if (pipe_reference_described(&(*ptr)->reference, &view->reference,
> (debug_reference_descriptor)debug_describe_sampler_view))</span ></pre>
