dd-out looks fine there. So I don't currently know how to reproduce

How about when you run the test with VERBOSE=yes?
If the failing test is in tests/dd/misc, you'd do this:
 make -C tests/dd check TESTS=misc VERBOSE=yes

Unfortunately, I cannot reproduce this seg fault any more. It's just fine now, also with snapshot 303. Several other tests fail due to broken seq as already discussed.


2 tests fail because on Interix '\' is not a valid filename character (other POSIX filename characters like '*' or '+' or '|' are fine), I removed those tests for me:

The test tests/rm/deep-1 seems to cause an infinite loop or something like that, I have to kill it always, so I disabled it for me, too.

The last lines in the test's log are:

++ exit 130
+ st=130
+ cleanup_
+ :
+ d=/srv/non-deb/coreutils/cu/tests/rm/cu-deep-1.kSpfDo3431
+ cd /srv/non-deb/coreutils/cu/tests/rm
+ chmod -R u+rwx /srv/non-deb/coreutils/cu/tests/rm/cu-deep-1.kSpfDo3431

So it seems to hang on cleanup, during chmod ... Didn't look into this to more detail yet.


The test tests/rm/dir-nonrecur shows IMO a real bug in coreutils, however:
"rm d" should fail at
remove.c:1094  with   "cannot remove 'd':  Is a directory"
but fails there with  "cannot remove 'd':  No such file or diectory"

If I remove the translation call _() around the text, then it fails correctly with "Is a directory". I think failures during translation shouldn't change the errno reported.
