The following code gives an assertion: (boost::format(""%s"") % """").str(); In debug mode, basic_string::append(0, 0) called from mk_str in feed_args.hpp is tested by the macro _DEBUG_POINTER, and decides the pointer is invalid even though the count is 0. I imagine this toxic behaviour is repeated in a number of places. It would be nice if the boost library could work around this problem at a low level. }}}",Bugs,closed,Boost 1.35.0,format,None,Problem,fixed,,
