Hi all,
This is probably an error of my own fault, but I’m not seeing what goes wrong currently.
I’m creating a TProfile from a th2d Histogram. Then I want to change the errors to RMS errors instead :
TProfile* projection_mc_sm_x_1=mc_sm->ProjectionY("mc_sm_px_1",1,1,"eo");
projection_mc_sm_x_1->BuildOptions(0,0,"s");I get an crash, which either displays:
*** Break *** segmentation violation

There was a crash.
