Hi Pádraig,

On glibc-2.31-5.fc32.x86_64 I'm seeing this test failure with coreutils,
since the tests are now checking for a specific errno.
I just checked a later Fedora 34 system which has the same issue.

For me, a testdir created through

    ./gnulib-tool --create-testdir --dir=../testdir --single-configure \
                   malloc-gnu realloc-gnu calloc-gnu reallocarray

passes all tests on Fedora 32 (glibc 2.31) and Fedora 33 (glibc 2.32).

Oh. Ah this issue is restricted to glibc's MALLOC_CHECK_ implementation.
The attached avoids this part of the test if it's being used.
I've reported the glibc bug at:

With this applied, your command above passes all tests.
