New submission from Carl Friedrich Bolz <cfb...@gmx.de>:
When unmarshalling a hand-written string it is possible to break the
invariants of longs:
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> x = marshal.loads('l\x02\x00\x00\x00\x00\x00\x00\x00')
>>> print x
00000
>>> x == 0
False
>>> bool(x)
True
>>> x + 1
1L
I would expect this to raise an error instead.
