I have built pandas from scratch in a new environment, then the problem is gone. that's weird... is there something like a side effect on pytest?

[dongho-jung]

I think there are some mismatches my pandas ( C compiled version ), Thus it seems to be a problem on my own, I'll close this issue.

(I think I forgot the rebuild pandas after the pull!)
