I guess pointing at the documentation of the proposed Boost Exception counts as generating buzz :)

The source code with boost-build jamfiles and tests can be downloaded here:

The source code is also available for online browsing:
Based on a quick read of the documentation: 1. What happens if a "boost::error_info" tag is used multiple times on the same object? Is it an error (exception or assert?), do the instances get combined like a multi-set, or do all instances besides the first (or last) get ignored/dropped? Shouldn't this be documented? 2. Shouldn't all inheritance of "boost::exception," especially via "enable_error_info," be of the virtual kind? Catching a given class type only works if it has exactly one connection to the actual exception object, which means that: a. The type is the final type of the object b. The type appears exactly once in the inheritance hierarchy c. All inheritance appearances of the type are virtual If a class type uses another type as a base multiple times, and at least one appearance is _not_ virtual, then catches with that base will be skipped when that first type is thrown. Imagine what happens if "enable_error_info" is applied multiple times during an exception session and/or the original exception object used "boost::exception". -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
