The following code produces a C4714 warning in Visual Studio 2010 with Boost 1.49 but not 1.48: ------------------------------------------------------------------------ ---------------------------------------- #include "stdafx.h" #include <boost/xpressive/xpressive.hpp> void main() { using namespace boost::xpressive; sregex pat1 = "foo" >> +space >> "bar"; // OK in 1.48, C4714 in 1.49 sregex pat2 = "foo" >> +space >> "bar" >> +space; // OK in 1.48, C4714 in 1.49 sregex pat3 = "foo" >> +space; // OK in 1.48, OK in 1.49 sregex pat4 = "foo" >> +space >> +digit; // OK in 1.48, OK in 1.49 sregex pat5 = +space >> "foo" >> +space; // OK in 1.48, C4714 in 1.49 } ------------------------------------------------------------------------ ---------------------------------------- System: Compiler: Visual Studio 2010 SP1 [Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86] Compiler warning level: /W4 OS: Windows 7 Professional 32-bit I would be OK with suppressing the warning, but I haven't been able to do so. Putting "#pragma warning(disable : 4714)" in my source file and in boost/xpressive/detail/core/ sub_match_vector.hpp and in boost/proto/transform/call.hpp does not suppress the warning. Using the "disable specific warnings" compiler switch /wd4714 also does not work.
