I have a flash file that has two combobox components on it. Both boxes have labels that are numeric. When the list is short - say 5 numbers in the box, the .swf compiles no problem, and the flash is well-behaved.

However, when I made both lists 10 entries long (values 2-10 for both), compiling the .swf put it into an endless loop. I ended up with a runtime error - "R6025 - pure virtual function call".

I spent a whole day isolating this problem, and I'm quite confident that it's a problem in the combobox rather than in other areas of my code.
