Boost.Stacktrace is a production-grade C++ library for capturing, storing, and printing backtraces (call stacks). It provides a header-only core with optional compiled backends that leverage platform-specific mechanisms: `_Unwind_Backtrace` (POSIX), `backtrace()` (glibc), `libbacktrace`, `addr2line`, or Windows Debug Engine (`dbgeng`). The library offers signal-safe raw dump functions, human-readable frame decoding (function names, source file, line number), and the ability to capture stacktraces at the point an exception is thrown via `from_current_exception()`. The design is modular, with separate compiled libraries for each backend and a no-op backend to disable tracing. The codebase is well-structured, heavily tested across compilers and platforms, and actively maintained. It demonstrates deep knowledge of C++ runtime internals, particularly in the exception interception implementation that hooks into `__cxa_allocate_exception` or uses vectored exception handlers on Windows. While the library itself is the reusable asset, several internal utilities (e.g., address base computation from `/proc/self/maps`, `dladdr` abstraction) embody patterns useful in other debugging and profiling tools.
