```
$ gcc -shared -o libex.so example.c -fsanitize=undefined
$ ldd libex.so
linux-vdso.so.1 (0x000079ecce133000)
libubsan.so.1 => /lib/x86_64-linux-gnu/libubsan.so.1 (0x000079eccda00000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x000079eccd600000)
libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x000079eccd200000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x000079ecce0df000)
/lib64/ld-linux-x86-64.so.2 (0x000079ecce135000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x000079eccd913000)
$ clang -shared -fsanitize=undefined -o libex.so example.c
$ ldd libex.so
linux-vdso.so.1 (0x000077ad748b4000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x000077ad74600000)
/lib64/ld-linux-x86-64.so.2 (0x000077ad748b6000)
```
As the result, when used with
`-Wl,--no-undefined` this breaks
on clang, but works properly with
gcc.
