[Bug libstdc++/26020] New: std::advance() isn't stable for floating point numbers

[Woebbeking at web dot de]

Hi,

i.e. code like

list<int> bla;
// insert some stuff into bla
list<int>::iterator it(bla.begin());
advance(it, bla.size() * 0.5);

can lead to an endless loop. I know that the code is "broken" but it should
work nevertheless. Please change the code to < 0 and > 0, not just while (n--).


Cheers,
André
