Hi,
Thank you for your answers.
Yes, your right, my program can't terminate. Maybe my example was not
good.
Here is another example where it still crash in my computer :
sys.setrecursionlimit(100000)
def rec(niter):
if niter == 0:
return
rec(niter-1)
rec(50000)
print "hello !" #will never print this !
I think it's not normal that it makes python crash, without saying
anything.
It should at least display what is the error (probably a stack
overflow here).
You can increase the stack size using "ulimit -s 500000". With this
setting your code runs for me.
A better idea is to avoid deep recursions, though. See
http://paulbutler.org/archives/tail-recursion-in-python/
for one approach how to implement tail recursion in python.
HTH,
