Package: libc6
Version: 2.31-9
Severity: important
Control: block 981899 with -1

One of the adequate autopkg tests now triggers an assertion in libc6,
which is a regression from buster.
I've extracted that test to build the attached self-contained reproducer.

sid$ make
mkdir -p tmp
# missing-version-information
cc -shared -Wl,--soname=libadequate-test-versionless.so.0 -Wl,--version-script=verscript-global lib.c -o tmp/libadequate-test-versionless.so.0

        /lib64/ld-linux-x86-64.so.2 (0x00007f6c563bd000)
Inconsistency detected by ld.so: dl-lookup.c: 111: check_match: Assertion `version->filename == NULL || ! _dl_name_match_p (version->filename, map)' failed!
make: *** [Makefile:13: all] Error 1

The test builds a binary that is linked against a shared library with
versioned symbols, but at runtime only a library with unversioned symbols
is available.
adequate then looks for the "no version information available" output, but
nevertheless expects ldd to not fail.
