Guys, while compiling this class:
I'm getting following log:
template<class T, int Min, int Max>
class Range
{
const T min_ = Min;
T max_ = Max;
};

As you see here one error is listed but this error isn't shown in a log. Any thoughts?
I think this may be a GCC bug (or feature). The message I get with 4.6.1 is;
err.cpp:4:24: sorry, unimplemented: non-static data member initializers
which as you can see isn't really a proper GCC error message - if it were, it would look like:
err.cpp:4:24: error: unimplemented non-static data member initializers
C:\Users\Art\Documents\code blocks\SafeInt\SafeInt\main.cpp:10:27: required from here
And I don't know what is your version of course.
Search the forum, there were some discussions about it....
