RipGrep musl binaries occasionally segfault during very-large searches

我遇到了其他问题。

您正在使用哪个版本的 ripgrep？

ripgrep 15.2.0（修订版 e89fff8）

功能：+pcre2
simd(编译):+SSE2,-SSSE3,-AVX2
simd(运行时):+SSE2,+SSSE3,+AVX2

PCRE2 10.45 可用（JIT 可用）

您是如何安装 ripgrep 的？

我最初在 OpenAI Codex 捆绑的 rg 中遇到了这个错误。该二进制文件与 https://github.com/BurntSushi/ripgrep/releases/download/15.2.0/ripgrep-15.2.0-x86_64-unknown-linux-musl.tar.gz 中的二进制文件完全相同，我已独立于 Codex 依赖重现了此错误。在下面的分析中，我通过 CROSS_CONTAINER_ENGINE=podman CARGO_PROFILE_RELEASE_DEBUG=true ~/.cargo/bin/cross build --release --target x86_64-unknown-linux-musl 构建了包含调试符号的 rg-15.2。

您在哪个操作系统上使用 ripgrep？

OpenSUSE Tumbleweed Linux x86_64

描述您的错误。

为 x86_64-unknown-linux-musl 构建的 Ripgrep 在以高并发度搜索超大目录树时偶尔会因 SIGSEGV 而崩溃。崩溃的代码行是 MUSL 的 mallocng 中关于堆元数据的完整性断言，位于 opendir 调用的 calloc 中。完整的回溯如下。

重现该行为的步骤是什么？

拥有足够大的搜索树似乎是重现的关键。运行附件中的 generate_repro_tree.py。这是一个 LLM 编写的程序，它会生成一个充满随机文件的树，其统计数据与我最初遇到该错误的仓库相似。它将生成一个包含约 20GiB 数据、180万个文件的树。

然后从该树的根目录运行 rg 循环，搜索树中不存在的任意字面字符串：while true; do rg tnoheueunotshisnthukoethnsueothnsiuothonesuioseuinth; done。在我的 24 核系统上，只要有足够空闲 RAM 让搜索树放入内核块缓存，通常大约一分钟就会出现 SIGSEGV。

实际行为是什么？

我得到一个具有以下回溯的 core dump：

以下是 core dump 和生成它的对应 rg 二进制文件。

预期行为是什么？

不应发生段错误。
