You can find the documentation at http://apolukhin.github.io/stacktrace/index.html and the github repo at https://github.com/apolukhin/stacktrace.
A few quick comments. 1. The library should try to not #include <windows.h> unless necessary. Constructing a stacktrace object and most of its operations besides operator<< / to_string do not need <windows.h> and it should be possible to avoid it. The functionality that needs <windows.h> needs to be defined in a separate header, for example <boost/stacktrace/output.hpp>. This allows use of the library in header-only mode while still isolating <windows.h> use into its own source file. For example, consider throw_with_trace in the documentation; the throw points, which in a header-only library will be in headers, do not need <windows.h> and should not drag it in. Only the catch point, which resides safely in its own source file, does. Incidentally, safe_dump_win.ipp includes <windows.h>, but does not need to. 2. There should exist a documented way to construct a stacktrace from an array of void const*. This is currently possible via from_dump, but it's not guaranteed to work; the format of the dump is technically an implementation detail of the library and may change. 3. detail::try_demangle is unnecessary, as it does the same thing as core::demangle. :-) Apart from that, looks like a substantial improvement. More comments and a vote possibly coming later.
