Backward Cpp
backward-cpp 是一个 C++ 堆栈跟踪库和调试工具，旨在捕获、解析并打印详细的执行轨迹和崩溃报告。它作为崩溃报告器和调用堆栈打印机，将原始内存地址转换为人类可读的函数名、文件名和行号。
该项目通过注册系统处理程序来处理致命错误（如段错误），从而实现自动崩溃报告，并在程序失败时自动生成执行轨迹。它的独特之处在于能从磁盘提取源代码片段，在解析后的堆栈帧旁显示具体的代码行。
该工具集涵盖了堆栈帧展开和内存地址解析，以分析导致崩溃的函数调用序列。它包括延迟符号翻译和彩色渲染功能，用于格式化终端输出的跟踪数据。
Features
- Crash Diagnostics - Provides a comprehensive system for capturing and printing detailed stack traces automatically during C++ fatal errors.
- Debug Symbol Resolvers - Translates raw memory addresses into human-readable function names and line numbers using system debug symbols.
- Stack Trace Capture - Snapshots the current execution stack or specific memory addresses for later resolution.
- Native Stack Unwinders - Traverses the current call stack to extract raw memory addresses of active function calls.
- Stack Trace Libraries - Provides a C++ library for capturing and rendering human-readable call stacks with embedded source code snippets.
- Symbolic Address Resolution - Transforms raw memory addresses into detailed information including filenames, line numbers, and inlined functions.
- Fatal Error Handlers - Registers system handlers to capture execution state automatically upon fatal errors like segmentation faults.
- Symbolic Backtrace Resolutions - Maps raw memory addresses to human-readable symbols and file paths during C++ program execution.
- Crash Reporters - Automates the capture and reporting of execution traces upon the occurrence of segmentation faults and fatal errors.
- Error Reporting - Generates formatted call stacks and source code snippets to help diagnose logic errors and application crashes.
- Application Stack Trace Capturers - Captures snapshots of the execution stack to analyze the sequence of function calls leading to a crash.
- Source Fragment Extractions - Reads original source files from disk to display specific lines of code alongside resolved stack frames.
