I think you have ill-formated Json in your commandblock. In these snapshots you need to specify each line on the sign, even if they are empty: so i tried your command in 15w39b and it crashed indeed. But after adding Text4 as in the command below, everything works fine. 

/setblock ~ ~-1 ~ minecraft:wall_sign 4 replace {Text1:"{\"text\":\"私の名刺に私は企業の社長です\"}",Text2:"{\"text\":\"私の心の中で私は開発者です\"}",Text3:"{\"text\":\"しかし、心で、私はゲーマーです\"}",Text4:"{\"text\":\"\"}"}

For me the issue is now fixed in 15w39b.
Everything seems to work fine, though I am only testing a sign. I do not get any chunk errors anymore.
Thanks!

For me it is definitely the sign.
After the chunk was regenerated nothing was inside and I could restart the server just fine. But with the sign in it, restarting the server will result in the chunk being regenerated again. I thought it might be a user spawned bat in it but I tried it serveral times with the bat and all went fine. So I am very certain that the sign causes the problem.

I will try to recreate this on a newly generated world in 15w36d and see if signs will work. Just to be absolutely sure!

I just had the same issue. I am using 15w36d on a localhost server.
For me it is definitely a sign, which is creating the issue. Though if it is placed nothing will happen. But as soon as I restart the server the chunks with signs will get corrupted and will be newly generated.
I don't know if I am doing something wrong. I am placing the signs with a commandblock:

This is the command I use:

/setblock ~ ~3 ~ minecraft:wall_sign 4 replace {Text1:"{\"text\":\"Ruhe in Frieden\"}",Text2:"{\"selector\":\"@a[score_TimeSinceDeath=0]\",\"bold\":true,\"color\":\"dark_blue\"}",Text3:"{\"text\":\"Dies ist Tod Nr.\",\"color\":\"white\"}",Text4:"{\"score\":{\"name\":\"@a[score_TimeSinceDeath=0]\",\"objective\":\"Deaths\"},\"color\":\"black\",\"bold\":true}"}

As mentioned before everything stays fine after running the command. No issues at all. But on a server restart the chunks containing the signs will be deleted.

This is the error message i get in the server console:
