Unfortunately, it does not appear to fix the bug.
I have reduced the test case to a single directory, which interestingly does
not appear to trigger the EUCLEAN error at all (though I expect it would soon,
had du not aborted).
Here's a full strace (hopefully enough to reproduce):

I attempted to fix the bug that leads to the abort by installing the following patch into Gnulib: https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=440b528b1d81dd31b2a2e4dde20d5c837c147811 and then propagating that into coreutils so that this should appear in the next coreutils release. Although this patch fixes two obvious bugs in the area, I can't easily test the patch in your situation, so please give it a try.

Or are you saying you want du to give you a nicer error message? --Apple-Mail=_80D26CEF-A09F-4E25-8B56-DB87A569095E Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- iNUEARYKAH0WIQQlpruI3Zt2TGtVQcJzhAn1IN+RkAUCY42uMV8UgAAAAAAuAChp c3N1ZXItZnByQG5vdGF0aW9ucy5vcGVucGdwLmZpZnRoaG9yc2VtYW4ubmV0MjVB NkJCODhERDlCNzY0QzZCNTU0MUMyNzM4NDA5RjUyMERGOTE5MAAKCRBzhAn1IN+R kNtpAQD+j+LFhrUdPWJE8uu0hfGXojy1qrLKo+rLa/erMRxe3wEA7I3LiEVG7193 AcHaIwpkoAWO3cTR70p9BDZsvPpJswo= =uLxa -----END PGP SIGNATURE----- --Apple-Mail=_80D26CEF-A09F-4E25-8B56-DB87A569095E--

Version: sys-apps/coreutils-9.1-r1 (Gentoo)
Context: Linux has a long-standing bug which leads to ext4 RAM dishs (zram
specifically) getting corrupted randomly. This manifests as various
newfstatat calls returning -1 errno=EUCLEAN (Structure needs cleaning).
The `du` tool, when it encounters them, prints an error as expected, but later
on aborts at:
#4 0x00007ffff7d4d3dc in __GI_abort () at abort.c:79
#5 0x000000010000ba08 in leave_dir (fts=fts@entry=0x100042680,
ent=ent@entry=0x100071630)
at lib/fts-cycle.c:136
#6 0x000000010000bd00 in fts_build (sp=sp@entry=0x100042680,
type=type@entry=3) at lib/fts.c:1326
#7 0x000000010000ce7c in rpl_fts_read (sp=0x100042680) at lib/fts.c:925
#8 0x0000000100004864 in du_files (files=<optimized out>,
bit_flags=<optimized out>) at src/du.c:691
#9 0x0000000100005cfc in main (argc=<optimized out>, argv=<optimized out>) at
src/du.c:1123
(I am not certain if the fstatat return value is related to the later abort,
because I couldn't find a way to get gdb to break only when fstatat returns
nonzero)
