# A stripped bzip2 build: what REA returned, checked against the source

請 REA 找出被剝除符號且最佳化的 bzip2 執行檔裡哪個函式印出某則訊息；結果與 24 個被呼叫函式皆和未剝除版本與原始碼吻合，文中也列出這個實驗證明不了的部分。

## 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.
