c++ - Why: vector crash when I try to push_back more than 16777216 -


i trying push_back instances of object vector (e.g. a; vectora.push_back(a)) code crashes whenever try push_back more once size of vector more 16777216 (16*1024*1024) (the capacity of vector 16777216 well, means vector reallocate memory).

anyone knows how should deal issue? checked memory used 320mb.

since std::vector wrapper around basic c array, has same limitations normal array, described here: is there max array length limit in c++? agree comments above contiguous memory limit. work around can switch using std::vector other class, not use arrays ( map, list or deque depending on needs ). solution using several vectors.

i trying var effect = new fx.morph(testmorph, { wait/delay 2 seconds before starting. ( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
