Broken: 2.72 RC1
Short description of error
It seems that the Array modifier's "Merge" feature is no longer correctly. It seems to skip over connecting every other generated copy?
Exact steps for others to reproduce the error
In the attached .blend file, take a look at the top of this Octopus in both 2.71 and 2.72. The effect of the breakage seems to be exaggerated when using "alt-a" to play back the animation in an OpenGL shading mode.
