i've always followed this rule myself. but it just occurs to me that there might be another way of looking at this. if our mythical program needs a fixed-size message buffer for every request, there are advantages to the stack. dynamic allocation with the pool library is slow and single-threaded. and of course, any dynamic allocation is more work and can be fatal. - erik
