#include <string>
// this global string causes gcov to think there's executable lines
// beyond the end of the file, and that they have not been executed
std::string globalVar = "";
std::string
doSomething()
{
// instantiating this string and calling a method on it causes the
// 'return' line to be marked as having never been executed
std::string localVar;
localVar.size();
return localVar;
}
int
main(int, char **)
{
doSomething();
return 0;
}
produces the wrong results:
a) it says that the return is never called
b) it executes past the end of the file
