It appears to be related to commit b959ed0c33ef28ec978689a8b1235661fcde93fe and specifically the change from code of the form return result-expression; to result_type r = result-expression; return r; which will fail for result_type void, as assignments are not permitted. A small test case that compiles in 1.57 but fails in 1.58 (gcc 4.8.2) is attached." Bugs closed To Be Determined phoenix Boost 1.58.0 Problem fixed
