<pre>(The Gallium HUD crash is "benign": you enabled more graphs than there are
pre-defined colors. Annoying, but unrelated to the problem at hand.)
My understanding is that malloc should return pointers with the largest
alignment requirement possible for the size that it allocates. Although,
perhaps that's less than 16 bytes on 32 bits?
Actually, I think that's it: the backtrace shows ctx=0x569cbfc8, i.e. ctx is
only 8-byte aligned even though it contains a pipe_blend_color structure.
Moving to Mesa core since it's not really radeonsi-specific.</pre>
