Problem with WHEN macro

[ghost]

I didn't realize the IF statement requires two expressions and when I did, I changed to a WHEN. After I did this, I kept getting a segmentation fault when running pharen. I changed the code back to using IFs and I still ended up getting segmentation faults.

Ok, I just tried to replace it with COND and appears that causes a segmentation fault. I think it's a problem with tail recursion but I'm not sure...

Could you post the code that's causing the problem? A segfault might be a problem in something else.
