I can reproduce this and it should get fixed once the patchset[1] to move
malloc debugging out into a separate DSO is pushed.

commit c142eb253f3814f46527e9b37484041dd85702cf

mcheck: Wean away from malloc hooks [BZ #23489]
Split the mcheck implementation into the debugging hooks and API so
that the API can be replicated in libc and libc_malloc_debug.so. The
libc APIs always result in failure.
The mcheck implementation has also been moved entirely into
libc_malloc_debug.so and with it, all of the hook initialization code
can now be moved into the debug library. Now the initialization can
be done independently of libc internals.
With this patch, libc_malloc_debug.so can no longer be used with older
libcs, which is not its goal anyway. tst-vfork3 breaks due to this
since it spawns shell scripts, which in turn execute using the system
glibc. Move the test to tests-container so that only the built glibc
is used.
This move also fixes bugs in the mcheck version of memalign and
realloc, thus allowing removal of the tests from tests-mcheck
exclusion list.

Can this be safely backported to the 2.33 branch?

I'm afraid not, the patchset introduces an ABI change. It may be possible to
isolate and backport some fixes for mcheck.
