[Python-Dev] python -O weirdness

[Vladimir Marangozov]

Strange. Can somebody confirm/refute, explain this behavior?

-------------[ bug.py ]------------
def f():
	pass

def g():
	a = 1
	b = 2

def h(): pass

def show(func):
	c = func.func_code
	print "(%d) %s: %d -> %s" % \
		(c.co_firstlineno, c.co_name, len(c.co_lnotab), repr(c.co_lnotab))

show(f)
show(g)
show(h)
-----------------------------------

~> python bug.py
(1) f: 2 -> '\003\001'
(4) g: 4 -> '\003\001\011\001'
(8) h: 2 -> '\003\000'

~> python -O bug.py
(1) f: 2 -> '\000\001'
(4) g: 4 -> '\000\001\006\001'
(1) f: 2 -> '\000\001'                   <=== ???
