There's already support for it.
https://www.boost.org/doc/libs/1_65_1/doc/html/stacktrace/getting_started.html#stacktrace.getting_started.exceptions_with_stacktrace

I never got the point of boost.exception though.
If you want exception info, just hook into your exception runtime and
get all of them, instead of just the ones thrown with the boost
exception magic.

Also you don't really need to do that for every throw, you only need
to do it if the throw is not matched to any catch or if the catch is a
special one.
There is special compiler magic that allows you to run code before
unwinding for specific catch sites.

What I personally do is that I go the extra mile: I generate a core
file, which is more useful than a stack trace.
That's a lot more expensive than just getting the stack though.
