syck.dump is broken

[anonymous]

syck.dump fails on even simple mappings:

>>> import syck
>>> doc = '''
... a: 1
... b: 2
... c: 3
... '''
>>> syck.load(doc)
{'a': 1, 'c': 3, 'b': 2}
>>> syck.dump(syck.load(doc))
'--- {}\n\n'
>>>

This is PySyck 0.61.2.

$ python --version
Python 2.5.2
$ uname -a
Linux brainsplit 2.6.24 #2 SMP Thu May 1 13:57:17 UTC 2008 x86_64 GNU/Linux
$ 

Cheers.

Works for me. What's the version of libsyck?

Are you running a 32-bit or 64-bit system? Perhaps it's a 64-bit issue?
