Dear all,
I am trying to run a compiled subroutine (.L -----.C+) I successfully used a year ago. I didn’t make any modification to the code or to the ROOT files required. Unfortunately, I have now an error and I do not understand what it means:
Here this is the print out in the terminal
Treating Brho = 1015
R__unzip: error -3 in inflate (zlib)
File : b1015light.root
And the corresponding piece of codes:
cout << " Treating Brho = " << Brho[i] << endl;
ostringstream data_file ;
data_file << "b" << Brho[i] << "light.root";
TFile *root_file = TFile::Open(data_file.str().c_str());
TTree *Tree_Data = (TTree*)root_file->Get(root_file->GetListOfKeys()->At(0)->GetName());
cout << " File : " << data_file.str() << endl;
The code ends with a segmentation violation a bit further (when I start to use the data contained in the tree). As I guess it a problem at the opening of the files.
So I tried to check the contain of the files with a TBrowser. For some of the Branches, I have a huge amount of error messages:
Error in <TBasket::ReadBasketBuffers>: fNbytes = 7648, fKeylen = 81, fObjlen = 11692, noutot = 0, nout=0, nin=7567, nbuf=11692
R__unzip: error -5 in inflate (zlib)or
R__unzip: error -3 in inflate (zlib)
Error in <TBasket::ReadBasketBuffers>: fNbytes = 7666, fKeylen = 80, fObjlen = 11692, noutot = 0, nout=0, nin=7586, nbuf=11692
Error in <TBasket::Streamer>: The value of fObjlen is incorrect (-552376725) ; trying to recover by setting it to zero
Error in <TBasket::Streamer>: The value of fNbytes is incorrect (-1782155502) ; trying to recover by setting it to zero
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
I tried with different ROOT files and the results is the same. I tried on different computers (Ubuntu 10.04 with ROOT 5.30 and Linux Mint Debian Edition with ROOT 5.32). Last time I used this code without any problem it was under Ubuntu 9.04 and ROOT 5.26/5.28.
If someone has a hint about what happens and at which level I have to investigate, thank you very much in advance.
Regards,
