TPad memory deallocation

ROOT

Could you please tell me what’s wrong with that c++ file?

I want to create an array of TPads and then deallocate them.

[code]#include <TCanvas.h>
#include <TPad.h>

int main(int argc, char* argv[]) {
TCanvas *c_tot = new TCanvas(“bih”,“boh”, 10, 10, 700, 500);

TPad **arr_overlay = new TPad *[2];

arr_overlay[0] = new TPad("overlay0","",0,0,1,1);
arr_overlay[0]->cd();
arr_overlay[1] = new TPad("overlay1","",0,0,1,1);
arr_overlay[1]->cd();

delete arr_overlay[0];
delete arr_overlay[1];

delete[] arr_overlay;

delete c_tot;

return 0;

}[/code]

the wrong part seems to be

delete arr_overlay[0]; delete arr_overlay[1];

caused by

but I can’t figure out the reason why.

The program starts but it crashes during execution.

Thank you!

After the line

TCanvas *c_tot = new TCanvas("bih","boh", 10, 10, 700, 500); add

c_tot->cd();
