Why calling sort() crashes?

[Kumar Anitesh]

Could anyone please help me to find why call to sort() is crashing at run-time in following code block:

string s = "Annnitttesrrh.";
vector vecChar(s.begin(), s.end());
sort(vecChar.begin(), vecChar.end(), greater_equal());

Am i missing something very basic ?

See the remarks for sort[^] and strict weak[^].

I think that equality don't work in sort. Why swap elements if they are equal?
