--- Comment #2 from Theodore Tso <tytso@....edu> ---
Using a stock ext4 file system ---- or an xfs file system --- results in the
same segfault in localdef.

So I think Christian is right.  This has nothing to do with ext4.

P.S.  I just tried with btrfs, and surprise!   localdef is also crashing with a
segfault.
