Node:Debugger options, Next:Evaluator options, Previous:Printing options, Up:Runtime Options
Here is the list of print options generated by typing
(debug-options 'full) in Guile. You can also see the default
stack 20000 Stack size limit (0 = no check). debug yes Use the debugging evaluator. backtrace no Show backtrace on error. depth 20 Maximal length of printed backtrace. maxdepth 1000 Maximal number of stored backtrace frames. frames 3 Maximum number of tail-recursive frames in backtrace. indent 10 Maximal indentation in backtrace. backwards no Display backtrace in anti-chronological order. procnames yes Record procedure names at definition. trace no *Trace mode. breakpoints no *Check for breakpoints. cheap yes *Flyweight representation of the stack at traps.
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 Proper tail recursion.
