            Bug ID: 28590
           Summary: dwz-0.14 FAIL: odr-struct-multifile.sh and
                    devel-ignore-locus.sh
           Product: dwz
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: default
          Assignee: nobody at sourceware dot org
          Reporter: vt at altlinux dot org
                CC: dwz at sourceware dot org
  Target Milestone: ---

`make check` reports two failures on ALT:

  builder@x86_64:~/RPM/BUILD/dwz-0.14$ grep FAIL dwz.log
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/odr-struct-multifile.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/devel-ignore-locus.sh

The same is with git master. Unfortunately, there is not much debugging output
in this test suite.

Manual run of failing part for odr-struct-multifile.sh:
```
builder@x86_64:~/RPM/BUILD/dwz-0.14/tmp.odr-struct-multifile.sh$ readelf -wi 1
| grep  'DW_AT_name.*:.*aaa'
    <29>   DW_AT_name        : (string) aaa
```

And the same for devel-ignore-locus.sh:
```
builder@x86_64:~/RPM/BUILD/dwz-0.14/tmp.devel-ignore-locus.sh$ readelf -wi 1 |
grep 'DW_AT_name.*: aaa'
builder@x86_64:~/RPM/BUILD/dwz-0.14/tmp.devel-ignore-locus.sh$ readelf -wi 1 |
grep 'aaa'
    <534>   DW_AT_name        : (string) aaa
    <556>   DW_AT_type        : (ref4) <0x533>, aaa

I think this just got fixed by:

commit b31d0ebd259a7037e43720cc9599ba37a283a698
Author: Lv Ying via Dwz <dwz@sourceware.org>
Date:   Thu Jan 13 05:29:44 2022 +0800

    Fix handling readelf following links by default

    The two testcases still failed when using newer readelf
    (binutils commit c46b706620e):
    testsuite/dwz.tests/odr-struct-multifile.sh
    testsuite/dwz.tests/cycle.sh

    fix the new -Wn readelf flag test

    Signed-off-by: Lv Ying <lvying6@huawei.com>

Could you retest?

--- Comment #5 from Vitaly Chikunov <vt at altlinux dot org> ---
While we are waiting for a fix there are 2 more failures appeared:

  FAIL:
/usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/two-files-low-mem-die-limit-0.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/odr-struct-multifile.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/devel-ignore-locus.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/cycle.sh

With the fix applied:

  FAIL:
/usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/two-files-low-mem-die-limit-0.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/devel-ignore-locus.sh
  FAIL: /usr/src/RPM/BUILD/dwz-0.14/testsuite/dwz.tests/cycle.sh

So one of originally reported bugs seems fixed.

ps. Also, in meantime we stopped to desire to use dwz for ALT Linux and deleted
the package. So the tests are - I temporary tried to rebuild the old package
and then rebuild after git merge of origin/master with the fix.

OK, shall we close this bug now then?
I don't see these failures on any other distro with current git.

Of course, since we stopped to build dwz, so I'm' closing it.
