- * Bug 25485: Browser/TorBrowser/Tor/libstdc++.so.6: version `CXXABI_1.3.11' not found
- * Bug 31646: Update abicheck to require newer libstdc++.so.6
- * This program is useful in determining if the libstdc++.so.6 installed
- * on the system is recent enough. Specifically this program requires
- * `GLIBCXX_3.4.25` which should be provided by libstdc++.so.6 from
- * gcc >= 8.0.0. If the program executes successfully, that means we
- * should use the system version of libstdc++.so.6 and if not, that means
- * we should use the bundled version.
- *
- * We use std::random_device::entropy() in order to require GLIBCXX_3.4.25:
- * https://github.com/gcc-mirror/gcc/blob/gcc-8_3_0-release/libstdc%2B%2B-v3/config/abi/pre/gnu.ver#L1978
