Dear All,
I am interested in studying memory usage in a variety of situations inside ROOT. Usually I do it with TObjectTable but it has come to my attention that the TMemStat might be better for studying memory footprints. However, when trying to instance a TMemStat object by using TMemStat mm("gnubuiltin"); or so, I get a bus error (reproduced below).
Do I miss a .rootrc option or perhaps a compilation option? When I tried enabling Root.TMemStat: 1 inside $ROOTSYS/etc/system.rootrc I also get a crash when starting root (probably the same crash as root initialization will probably try instancing the TMemStat…).
My operating system is MAC OS X 10.8.2 and I’m running ROOT v5-34-05…
Many thanks for all help!
Best Regards,
David
Bus Error:
[code]root [0] TMemStat mm(“gnubuiltin”);

There was a crash (kSigBus).
