A quick check shows that beta 4 also fails, but in a very different way.
The 150 eval results start to stream up the message pane, but after a
while the shapes of the characters become distorted. A while later the
colour of the characters changes from white to dark grey. Finally
PVENGINE crashes with "an invalid page fault in module <unknown>".
Sometimes other running programmes also get knocked over.

POV 3.5b5 behaves as described by Marc-Hendrik.

It's just a wild guess, but perhaps there's some limitation to the
amount of text that can be displayed on the message pane after rendering
has completed. Each of the 150 evaluates causes 7 lines of text and two
horizontal separators to be displayed on the message pane.
