root4star [4] 

--> still negative memory allocated but no more crash (and the memory goes back to 0)
--> to use memory stat :

1. in the includes : #include "TMemStat.h"
2. at the beginning of your code ( generally before a loop ) : StMemStat mem;
3. to display : std::cout << " current memory : "<< mem.Used() << std::endl;

• GDB

to run GDB with a BFC chain already setup :

1. at the prompt : root4star gdb
2. run myMacro.C

where myMacro.C looks like (for example) :

.x StRoot/macros/bfc.C(1,10,"y2013,AgML,ITTF,Sti,tpcI,TpcFastSim,pxlFastSim,-ssdfast,VFMCE,McEvent,geant,IdTruth
,fzin,StiRnd,PixelIT,-IstIT,NoSvtIt,NoSsdIt,StiPulls,analysis,tags,clearmem,evout,McEvOut,
MiniMcMk,McAna,MakeEvent","debug.fz") 

## how to commit ## 

1. cvs add offline/hft/StRoot/yourMaker
2. cvs add offline/hft/StRoot/yourMaker/*.* (each file)
3. cvs commit offline/hft/StRoot/yourMaker

## if maker does not exist in the branch ##

1) mkdir offline/hft/StRoot/StSsdDbMaker
2) cvs add offline/hft/StRoot/StSsdDbMaker // this adds the maker in the StRoot branch
3) copy code
4) cvs add offline/hft/StRoot/StSsdDbMaker/*.* (each file)
5) cvs commit offline/hft/StRoot/StSsdDbMaker
