Here is a little more information: this happens with VC++ express 2008. It
originally happend with a severity_logger_mt when Qt issued a qWarning()
after main() returned from within a destructor and I wanted to log that
warning. The access violation was within some mutex/lock code from
boost::thread, but I also saw it fail in boost::intrusive or other libs
boost::log was using depending on how I moved code around. I'll try to
provide a trace on monday.
