Hello,

This thread reminds me the following thread I had started:

http://thread.gmane.org/gmane.comp.lib.boost.devel/209982

 
Also the code had improved since than:


https://sourceforge.net/p/cppcms/code/2238/tree/framework/trunk/booster/booster/backtrace.h
https://sourceforge.net/p/cppcms/code/2238/tree/framework/trunk/booster/lib/backtrace/src/backtrace.cpp


Several notes:

bfd library is GPL license which would be a major drawback.

Also I noticed that you use mostly glibc's backtrace.
I don't know at what level your code is gblic specific but backtrace 

is avalible on many platforms like Solaris and latests Mac OS X's

You can also use _Unwind_Backtrace function that is much widely supported. Also
on some platforms backtrace provided by libexec (like FreeBSD) is quite broken.

Additionally I noticed that you use ::StackWalk64 AFAIK it is not thread safe function.
I see that you wrap everything with a mutex which makes the library much slower.

I'd suggest to use RtlCaptureStackBackTrace instead.

You can also utilize function like backtrace_symbols. AFAIR not every platform has
dladdr (Solaris if I recall correctly)


Generally it is very interesting topic and very useful stuff (from my experience
in deploy with CppCMS).

I'd suggest:

1. Take a look on my code, you probably can improve platform support
2. Try to integrate the code with throwing an exception which would make it
   much more useful.
