Dear Maintainer,

I have not used ffmpeg in a while, so I cannot say how new this is,
but, as the title says, today, if I try to run ffmpgeg, ffprobe or
ffplay, even with just the '-version' flag, I get the same response:

	$ ffmpeg -version
	Bus error

This happens only on this one system. I have another system which
is also a Debian Testing, and there things do work.

I have tried to debug this, but to no avail:

$ gdb /usr/bin/ffmpeg

I've also tried running the same with a user which never used
ffmpeg before, to account for some settings if relevant. Same.

I am at a loss on how to debug this further.

Thanks in advance for your attention and help,

       Shai.

The error I encountered was followed by a set of other weird errors in
other programs, and apparently it was all caused by a bad disk.

Sorry for the noise,

Shai.
