我的应用正在使用boost::program_options并触发了AddressSanitizer＆＃34;堆栈缓冲区溢出＆＃34;从异常中生成错误消息。
我并不担心增强错误 - 功能正常，这只是在非生产应用程序的命令行解析部分。但是，我想要取消AddressSanitizer消息。

我尝试过使用ASAN_OPTIONS抑制文件方法，但这似乎只支持很短的错误类型列表（例如＆＃34; vptr_check＆＃34;＆＃34;泄漏＆＃34;）。
答案 0 :(得分：1)
我认为没有一种简单的方法来抑制这个错误 - Asan的Clang版本具有黑名单机制，但是它的上下文不敏感所以你必须在std :: string的所有用法中禁用内存检查，这是非常不受欢迎的。
一个选项是使用-fsanitize-recover = address编译器标志并将halt_on_error = 0添加到您的ASAN_OPTIONS（有关详细信息，请参阅wiki，并注意只支持恢复相对较新的GCC和Clang）。这将在第一次错误后继续执行。然后，您将能够检查完整的Asan报告并选择您感兴趣的内容。
