Description (last modified by )
Since Microsoft have deprecated most of the standard library, their debug libraries also check for unsafe pointers. The following code gives an assertion: (boost::format("%s") % "").str(); In debug mode, basic_string<char>::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.

Logged In: YES user_id=1562825 Originator: NO This will also happen with an empty string (instead of just a character array/pointer) std::string my_string; (boost::format("%1%") % my_string).str();

This appear to be fixed (and tested for) in SVN Trunk. So I'm closing the issue down: please reopen if it resurfaces.
