What does this mean?

I've recently received an automated email with the following message:  

*** glibc detected *** corrupted double-linked list: 0x08aa8f20 ***

What does this mean, and how do I fix it if I need to?

Thanks

ray\modules\global\app\ffmpeg.exe

its some of error of this module

recheck capability your current ffmpeg and your host system

.. you also can write to ffmpeg developers support about such problems
