【未解決 / Workaround】GNU MakeにClangのアドレスサニタイザーを使うとdetected memory leaks
環境
ubuntu@codespaces-7df36e:/workspace$ clang-20 --version
Ubuntu clang version 20.1.8 (0ubuntu4)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/lib/llvm-20/bin
症状
Bazelで以下のHardeningを設定してツールチェーンをビルドする。
build --copt=-fstack-protector-strong
build --host_copt=-fstack-clash-protection
build --host_copt=-D_FORTIFY_SOURCE=3
build --host_copt=-fsanitize=address,undefined
build --host_linkopt=-fsanitize=address,undefined
以下のエラーを吐いてGNU Makeがコケることがある。

SUMMARY: AddressSanitizer: 46454 byte(s) leaked in 325 allocation(s).
Workaround
アドレスサニタイザーを諦めて、fsanitizeをboundsにする。
メモリリークの検知はされないが、配列の境界外アクセスは検知してくれる。
build --host_copt=-fsanitize=bounds,undefined
build --host_linkopt=-fsanitize=bounds,undefined
おそらくGNU Make側のバグ、もしくはトリッキーなコードが原因だと思われる。こちらで対処できることはあまりない。（Clangのアドレスサニタイザー側の問題な可能性も一応はある）
