%%%--- Operating System, Graphics card ---

- Blender version with error, and version that worked ---

Broken in 2.66a and 2.65, no adaptive domain before that.

- Short description of error ---

If adaptive domain and high-resolution are both enabled in the smoke simulator, the adaptive domain area is based on the low resolution smoke. Since high resolution behaves differently, parts of the high resolution smoke suddenly vanish as the low resolution smoke dissolves. This is likely more pronounced when "dissolve" is enabled.

(Image "1" is frame 61, image "2" is frame 62. The adaptive domain is shrinking back to the emitter.)

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Create a smoke simulation with adaptive domain, high-res 2, and dissolve 5. Emit the smoke in a burst, and then check near the end of the smoke dissolving.
If you bake from my blend file, the bug occurs on frames 61-62.
