Read the rest of the thread -- it didn't look like a bug to me.

I'm confused. I said it didn't look like a bug because the rectangles
are inclusive. You said (I think) it does look like a bug because the
rectangles are inclusive. Anuj's last reply says
_mesa_regions_overlap() is wrong for rectangles that share an edge...

But if the bounds are inclusive, and rectangles share an edge...
doesn't that mean the regions overlap?
