Thanks.
I too have reproduced it, now.
FYI, this bug was defined away with my rewrite to make fts.c
avoid using fchdir/chdir -- to be checked in soon, but
only for coreutils-6.x.
Test case coming up...
Here's the fix that will be in coreutils-5.94:
2006-01-10 Jim Meyering <[EMAIL PROTECTED]>
Avoid the double-free (first in fts_read, second in fts_close) that
would occur when an `active' directory is made inaccessible (e.g.,
via chmod a-x) during a traversal.
* fts.c (fts_read): After a failed fchdir, update sp->fts_cur
before returning. Reproduce this failure by
mkdir -p a/b; cd a; chmod a-x . b
Reported by Stavros Passas.
