strange problem with RtlCompareUnicodeString

[Ivan Leo Puoti]

RtlCompareUnicodeString should return 0 if it receives two identical string.
But for some strange reason this code
http://rafb.net/paste/results/e3tHCg40.html
prints this output
http://rafb.net/paste/results/SS5U2N81.html
Is it a mistake I've missed, or is this a bug in the implementation of RtlCompareUnicodeString?

Ivan.

Solution: the function checks the Length member of the struct,
not the real length of the string.
