default value under linux

[Onyxx]

I kind of remember that in the following function signature, the optional input param will always be equal to its default value under Linux.

int funct(const int param = 1)
{

}

So basically the following function would always return 1 on Linux.

int funct(const int param = 1)
{
return param;
}

I think it is because the compiler is doing some optimization.

Or may be it was a similar case ... Does someone know in which situation this would happen ?

It can only happen if you have a seriously broken compiler.
And it seems unlikely that g++ has had such a bug in the last decade,
although perhaps a superficially similar case could have.

Why are you asking, by the way? Are you really trying to ask about
something else, such as whether Linux is a useful platform, or g++ a
useful compiler?

I remember vaguely a similar bug that I had on Linux but not on Windows. Itshould have been something different.

Thanks for the answer
