I see:
0000052c g F .text 00000070 _vgnU_freeres
which might be related to an intended replacement for __libc_freeres.

When I run "readelf --all /lib/libc.so.6" on x86_64 then I see:
6489: 472f4e50 129 FUNC GLOBAL DEFAULT 13 __libc_freeres
so that symbol is in glibc-2.13.
What is the output from:
$ ldd ./hello-arm-bionic ### print the shared libs needed by the app
and what is the status of __libc_freeres with respect to each of the
libraries named by ldd?
At the time that memcheck fails, which files are mapped?
$ cat /proc/<pid>/maps
