Thats the problem I just don't know. what you have will have been built 
by a packager for a distribution, it may have taken released source, or 
it may have taken the source before it was released. I would expect its 
later, but I can't say for certain. But either way its several years old 
now. I have had a more recient report of truncated files, but nothing 
else. If I had a easy fix I would suggest it. But I do know that its not 
that common, so if its a unixODBC problem it will need luck and lots 
more reports to try and track it down :-(

The simple fix for you should be to make the file read only to any user 
that will be running unixODBC.
