runtime error as of this morning

Question

As of this morning I'm seeing a runtime error from xocc and vivado that I've never seen before. I created a fresh F1 instance and still see this running the helloworld_ocl example.   
  
Is this a known issue?

Hello,  
I just tried this on a fresh instance (using ssh), and it works for me.  
My Kernel version is:

```
> uname -r 
3.10.0-957.5.1.el7.x86_64
 ```

Please check you are using the same Kernel version.  
  
There have been a couple of forum posts earlier with a similar error message :

-Thanks

I found that if I launch vnc and run it in an X-windows environment then it seems to work.   
  
Do I need to do anything special for a batch (plain ssh) environment?   
  
Thanks

Answer

Looks like it: 3.10.0-957.5.1.el7.x86_64

I seem to have found a workaround to the issue on google:   
  
 export LC_ALL=C; unset LANGUAGE
