First of all you have following problem in you analysis, where %CODE{"cpp"}% delete myHades; %ENDCODE% is called. I get following error:
*Segmentation fault (core dumped)*

If you start debugger and make backtrace, you get:
#0 0xb66d8227 in HMdcTrackGCorrPar::~HMdcTrackGCorrPar () at TString.h:293
#1 0xb7a528e2 in TCollection::GarbageCollect () from /usr/local/opt/root/403-02/lib/libCore.so

#6 0x0804cea0 in main (argc=3, argv=0xbfa79194) at stdlib.h:398

To comment out several lines out in destructor of HMdcTrackGCorrPar (before I tried to set the pointers to NULL, e.g. %CODE{"cpp"}%corrScan0 = NULL;%ENDCODE%; unfortunately didn't help)
%CODE{"cpp"}% HMdcTrackGCorrPar::~HMdcTrackGCorrPar() { if(fieldmap) delete fieldmap; if(corr) delete corr; if(corr1) delete corr1; // if(corrScan0) delete corrScan0; // if(corrScan1) delete corrScan1; // if(corrScan2) delete corrScan2; if(spline) delete spline; } %ENDCODE%

does not help really, you get following error:
* glibc detected * double free or corruption (prev): 0x09f0fd38 ***
Aborted (core dumped)

and the corresponding BackTrace in debbuger looks like:

Next point of investigation was to check destructors of HKickTrackFB and HMdcTrackGSpline
