Clang の AddressSanitizer を有効にしたバイナリを valgrind でチェックしたらエラーになる
========================================================================================

Clang の
`AddressSanitizer <https://clang.llvm.org/docs/AddressSanitizer.html>`_
を適用したバイナリを
`valgrind <https://valgrind.org/>`_
でチェックしたところ、
次のようなエラーになった。

AddressSanitizer と valgrind を一緒に使用するのは良くないらしい。
