Hi Takatoshi,

yes it's definitely a bug :(
My fix was not completely correct. I gave it another try (rev. 74046).
I unfortunately have right now some... ehm disagreement with my Visual 
Studio so I didn't run my full tests but I think it must now be correct.
Could you give it a try?

Thanks,
Christophe
