--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
LGTM. But as I said, it could be useful to look for other symbols too.
Looking at i686 glibc, I see
for j in /lib/libc.so.6 /lib/libpthread.so.0 /lib/libm.so.6; do for i in
`readelf -Ws $j | grep -v ' UND ' | awk '{print $8}' | grep -v GLIBC_PRIVATE |
grep '[^@]@[^@]' | sed 's/@.*$//' | sort -u`; do readelf -Ws $j | grep -v ' UND
' | awk '{print $8}' | grep -v GLIBC_PRIVATE | grep -q ^${i}@@ && echo $i;
done; done

On x86_64:

So, which of these are interposed by sanitizers?
