Hallo Mohammad,
just a remark on the -O2 flag: it is connected only to the wrong values of the slopes Sebastian was talking about, not to the crash of the code.
In fact, running just his simplified code:
// Setup a trackrep which uses geane
CbmGeanePro* gePro=new CbmGeanePro();
CbmTrackParP dummy;
TVector3 pos(0.1,0.1,0.1);
TVector3 mom(0.1,0.1,1.);
TVector3 poserr=TVector3(0.1,0.1,0.1);
TVector3 momerr=0.2*mom;
DetPlane initplane(TVector3(pos),TVector3(1.,0.,0.),TVector3(0.,1.,0.));
double q=-1;
CbmTrackParP par(pos,mom,poserr,momerr,q, initplane.getO(),initplane.getU(),initplane.getV());
par.Print();
here is what I get:
1) if I run it with the Check_Compiler and with the -O2 flag, I get the wrong values of the slopes dx/dz and dy/dz (the same values Sebastian talked about)
2) if I run it with the macro but deleting the -O2 flag in CMAKE_CXX_FLAGS_DEBUG, I get the correct values of the slopes.
I am using Scientific Linux CERN SLC 4.6, gcc 3.4.6.
Best regards,
Lia.
