6374	operator << for exception doesn't work with 0/1 length tuples	edA-qa mort-ora-y <edA-qa@…>	Emil Dotchevski	"The operator<< for boost exception allows attaching error_info structures. As a convenience it also takes a tuple form of those info structures.  This tuple form does not work if the tuple is empty (0-length) or also if it is 1-length.

This is a compile-time matching issue.

The attached code shows the compile error (reduced to the essentials).  It also includes the workaround which I am currently using (compile with WORKAROUND defined). Ideally the non-workaround version should work.

NOTE: This doesn't appear related to the macro itself. If you simple instantiate the exception and error_info tuple and use the operator directly the same compile-time error occurs. I've left the MACRO form to show the intent."	Bugs	closed	To Be Determined	exception	Boost 1.46.1	Problem	fixed
