Stack overflow errors are caused by a computation trying to use more
stack space than has been enabled by the
stack option. They are
reported like this:
(non-tail-recursive-factorial 500) -| ERROR: Stack overflow ABORT: (stack-overflow)
If you get an error like this, you can either try rewriting your code to
use less stack space, or increase the maximum stack size. To increase
the maximum stack size, use
debug-set!, for example:
(debug-set! stack 200000) => (show-file-name #t stack 200000 debug backtrace depth 20 maxdepth 1000 frames 3 indent 10 width 79 procnames cheap) (non-tail-recursive-factorial 500) => 122013682599111006870123878542304692625357434...
If you prefer to try rewriting your code, you may be able to save stack space by making some of your procedures tail recursive. For a description of what this means, see section `Proper tail recursion' in The Revised^5 Report on Scheme.
