I would say that recursion can be problematic. Notice my C++ code... 
Luckily, it had a single recursive call to ct_fwave that only modified 
the wave parameter. This particular type of recursion does not need to 
be there at all. So, I converted it to a purely iterative function that 
does not need any allocations.

Now, sometimes, based on the "nature" of the recursion, well, the fix 
that I used for my code does not apply in all cases. Sometimes, we need 
to create an artificial stack to store nodes in an iterative algorithm 
in order to replace the actual recursion. Heck, I would rather iterate 
over a n-ary tree stored in a 1-d array than go through any recursive 
tree traversal.

Compiler driven optimization techniques aside for a moment, I still 
agree with John in the sense that iteration can be safer than recursion.
