Sorry, run was meant to be num, it was a typo.
This is the last incarnation of that template function:
template <class T>
const std::string toString(const T & data){
std::stringstream num(std::stringstream::out);
num << data;
return num.str();
}
Nevertheless, the application compiles and runs as expected, as long as the gtkmm property sheet is not added to the project, otherwise, the application crashes. I have been testing gui-toolkits for the past few weeks and none delivered what they promised. They don't install properly or they don't run properly, and some even leak badly. Microsoft GUIs are a bit complicated and bulky, but, like Java, it delivers what it says it will.
Some times I don't understand why I put myself in these situations, where I am testing and trouble shooting other people's applications, when all I want to do is write code and trouble shoot *my own applications*.
I am a sucker for punishment I guess.

This is a C++ issue, not a GCC issue.

Looks like problematic code to me.
This function is returning a reference to an object, but the implementation is returning a temporary.
Additionally, line 5 lists a variable 'run' which isn't declared anywhere in your sample.

If you're looking for an output string stream, consider using a std::ostringstream.
