terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

QTimer timer = new QTimer(this);
timer->start(1000);
connect(timer,SIGNAL(timeout()),this,SLOT(updateTimer()));

Every 1 second, function works.
my system the linux. Runs suddenly dies.

-----global-------
static int arrayNum[33000];
-------------------

updateTimer(){
unsigned short int** US_INT;
US_INT= new unsigned short int*[255];
for(int i = 0; i < 255; i++)
{
US_INT[i] = new unsigned short int[128];
memset(US_INT[i], 0, sizeof(unsigned short int) * 128);
}
double x;
double y;
int cnt= 0;
int nArrayCount=0;
for(int i = 0; i < 255; i++)
{

            for(int j=0;j<128;j++){

                x=j;
y=cnt
                nArray[nArrayCount]=US_INT[i][j];

                nArrayCount++;

            }
            cnt=cnt+(256/255); 

        }


 for(int i = 0; i < 255; i++)
        {
            delete US_INT[i];
        }

        delete[] US_INT;

}
program stop. and message↓

Hi
It might be one of you new statements
you can try

try {
code using new
}
catch (const std::bad_alloc&) {
qDebug() << "alloc error";
}

also the arrayNum[33000];
what do u u do with it?
You use nArray in function. is that arrayNum ?

@ForestPoem said:

nArray

thanks.

nArray = arrayNum

It's my mistake. The two are the same
