warning: broken MIR (occurs when compiling any of the examples on rustc stable 1.8)

I don't know if this matters, but thought I'd let you know. The all_widgets example seemed to run okay except that I couldn't change the numbers for frame height or width in the GUI: I tried using the mouse wheel, clicking above, below, and on the number, typing a number and none had any effect.

The same warning also occurs with canvas, primitives, and text. Incidentally, the text example is very slow to resize (I'm on a 3+GHz i7).

Thanks @mark-summerfield, I reported this a while ago to the core team and they seem to be aware of it, I'm guessing the warning will go away in one of the upcoming stable rustc releases 👍

Thanks for the report, I'll leave this open for others to see until the next rustc comes out and the warning goes away.
