Re: [Boost-users] boost::format warning

Its implementation defined whether the evaluation of c==42 will happen before or after the evaluation of c++. I am happy to see a compiler that does emit a warning on this kind of code. Simply modify your code like this boost::format("%1% %2%") % (c==42) % c; c++; or this c++; boost::format("%1% %2%") % (c==42) % c; depending on what you actually intended.

Thanks for pointing this out. And sorry to spam the boost mailing list, for this unrelated question (as I know now). Henning
