[Message part 1 (text/plain, inline)]

Program 'find' failed even -ignore_readdir_race  (no *OK* in output):

> mkdir -p 1/2/bla 3/4/bla ; { find . -ignore_readdir_race -mindepth 1
-name '[0-9]' -print -exec stat --format "%s %n" {} \; -exec sleep 0.5 \;
&& echo OK; } & sleep .2 ; rm -fr 1 3 ; wait
[1] 25831
./3
4096 ./3
find: `./3': No such file or directory
./1
stat: cannot stat ‘./1’: No such file or directory
[1]+  Exit 1                  { find . -ignore_readdir_race -mindepth 1
-name '[0-9]' -print -exec stat --format "%s %n" {} \; -exec sleep 0.5 \;
&& echo OK; }


Program `find` succeed even -noignore_readdir_race but with -depth option:

> mkdir -p 1/2/bla 3/4/bla ; { find . -depth -noignore_readdir_race
-mindepth 1 -name '[0-9]' -print -exec stat --format "%s %n" {} \; -exec
sleep 0.5 \; && echo OK; } & sleep .2 ; rm -fr 1 3 ; wait
[1] 25854
./3/4
4096 ./3/4
./3
stat: cannot stat ‘./3’: No such file or directory
./1
stat: cannot stat ‘./1’: No such file or directory
*OK*
[1]+  Done                    { find . -depth -noignore_readdir_race
-mindepth 1 -name '[0-9]' -print -exec stat --format "%s %n" {} \; -exec
sleep 0.5 \; && echo OK; }

You've reached the coreutils mailing list, but 'find' is part of the
findutils. You'll want to report this bug there (that project uses a
different tracker, so I can't just reassign this bug between projects
within the debbugs database).
https://savannah.gnu.org/bugs/?group=findutils

I'm closing this bug out in debbugs as it is not a coreutils issue, even
though it does look like you may have found a valid issue in findutils.
