You're right, it could be a library problem. The test suite's LD_PRELOAD library 
just returns what the C library gives it, though. Perhaps LD_PRELOAD usage is 
messing up malloc on your platform, so that it returns improperly-aligned 
pointers? You might try something like the attached patch to see whether the C 
library is doing that.

Yes, one would think so.

In any case, this is not sounding like a bug in coreutils itself.
