I think it's a problem triggered by "-malign-double" optimization. It looks 
like that lstat returns a stat structure with some garbled fields (notably 
st_size and st_blksize).

This little test was performed with both 5.0 and latest CVS, on an i686 
(Celeron Coppermine) host running debian unstable, using gcc 3.3.2

~/src/coreutils-5.0 $ ./configure CFLAGS="-malign-double" && make
[...]
~/src/coreutils-5.0 $ ./src/ls -l

I am currently investigating, but I couldn't reproduce it with a tiny program 
using lstat.

Best regards,
