Dear co-rooters,
I am facing a rather bizarre issue. I am processing some data and when adding a TH2F histogram I get a segmentation error. The only relevant info that I get concerns the second argument of my macro which is a TString
#17 0x00007fc97188f9fb in analyser (filename_in=..., filename_out=<incomplete type>) at /eos/home-a/astamato/./analyser_orela.C:268
This points out to the line where the histogram is written with the Write() function. When I change this histogram to a TH1F everything works fine but I don’t understand why. Note that I have enough quota to write the output root file. In addition I run the macro with valgrind to check if I have a memory leak somewhere, but I can’t find anything there as well. The output of valgrind is at the end of the post. My macro is the following
#include "TH1.h"

#include "TString.h"
