# 一个被剥离符号的 bzip2 构建：REA 返回了什么，并与源代码核对

向 REA 询问在一个被剥离符号、经过优化的 bzip2 二进制文件中，哪个函数打印了一条消息；其答案及 24 个被调用函数与未剥离符号的构建及源代码一致，文章列出了这并不能证明什么。

## Description

为什么列出它：开源目标，对照已知源代码进行了仔细验证。

## Original README

Asks REA which function prints one message in a stripped, optimised bzip2 binary; the answer and 24 callees matched an unstripped build and the source, and the post lists what this does not prove.

Why it is listed: Open-source target, careful verification against the known source.
