I do know Boost.Stacktrace calls addr2line too. From the code(https://github.com/boostorg/stacktrace/blob/develop/include/boost/stacktrace/detail/addr2line_impls.hpp https://github.com/boostorg/stacktrace/blob/develop/include/...), it seems Boost.Stacktrace also shells out to addr2line for every address. But in practice, I found the overhead of boost::stacktrace::stacktrace() is not as horrendous as my crappy implementation, which calls addr2line, too. Is there something I missed in Boost's code?
