RE: [boost] improved assertions?

I'm working on a Boost.StackTrace library.  There's a Win32 implementation
in the Files area, StackTraces/Win32_StackWalk.zip.  The idea I'm going with
is to define a generic Boost.StackTrace API, and then layer the Boost.Assert
API on top of that.

Currently, it should work for MSVC, BCB6, and I think BCB5.  I haven't
evaluated yet what it might take to work for GCC on Win32.  I'm currently
working on the BCB tool so that it will be more flexible (work for BCB 3-5
and more likely to work with future versions).  After that, I'll see what's
necessary for GCC/Win32 support.

As for other platforms, the Boost.StackTrace API should be fairly simple to
implement on Linux, etc.  Easier than Win32.

There's a "docs.txt" in the zip file that covers the Boost.StackTrace API,
the Win32 extensions to the Boost.StackTrace API, and compiler-specific
notes (just Borland for now).

Did anything ever come of this? I'd really love to see improved assertions
on platforms which can support them also!

Oh, if I remember correctly, this project degenerated when people began
pursuing intrusive-yet-portable designs that require users to add cruft to
every function in order to get a backtrace... at least, that's when I lost
interest.

Well, allow me to restate my interest in seeing a library which takes
advantage of platform-specific facilities to produce a backtrace
non-intrusively.
