IVF vs other compilers -- size of executables

In particular, I notice that the size of my executable using CVF is about 13MB. For IVF, the same executable is over 30MB. This is using similar, if not exactly the same, compiler options.
Is there something I'm missing in link options between the two?

I'll bet you have bounds checking enabled. That will dramatically inflate the executable size. It's on our list to look at, but at present, since no customer has complained that I know of, it's not been given a high priority.
The size is not in code but in data - text for the message that is displayed. The compiler could be smarter in reducing duplication of the text.

I did have bounds checking enabled -- I'm recompiling now to see what taking it out does. It did indeed help -- now at 6MB for IVF. (I will do CVF later)
Of course, I have it enabled in the other compilers as well. What happens if you turn it off and have a array out of bounds error? (I do still have trace enabled.)

If you have bounds checking off and exceed array or stringbounds, the results are unpredictable.
