Probably No, I also suspected it in the beginning. However, char.diff was not created
by some strange condition. I think that WIFEXITED showed the strange condition.
In the place which I showed above, diff makes char.diff from the Manual operation.
I expect that it is related to a system() call.

I am investigating in some other environments. now...
However, It does not clarify yet..:-(
