I am running on [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on linux2
and your script DOESN'T crash.
I am a notSoNewPythonWriter/longTimeC++Writer and I am always
concern about memory(I guess like anybody).
I just started writing a big app in python, and for
now I decided to not be to worry about memory and to rely as much as
possible on python.
My question is simple: Will it crash the same way if the range call what
in a function and I let python cleanning after itself:
def doStuff(x):
o = None
for i in xrange(x):
o = foo(o)
# x = 43550
x = 3
doStuff(x)
print "I'm fine."
doStuff(x+1)
print "I'm dead."
