That's a big can of worms... You'd have to maintain the lifetime of
the infos manually.

Why do you want to make the infos global anyway? After all, their
lifetime should be identical to the lifetime of the exception object
itself; the easiest way to accomplish this is to use a member of the
exception object to store the info.
