Re: Building ROOT from source on Fedora 11

Hi Rene,

Sorry for the delay, I am on the west coast of Canada. :\

I have attached a file with all the particulars about the build environment and the options I used to build ROOT. It also includes the backtrace from the segfault. I have also attached the log file generated by valgrind. I used the following command to attach valgrind to root.

>$ valgrind -v --log-file=valgrind-root.log root -l MonitorESD_91890_1.root

As reported earlier, after the segfault I had to kill ROOT with $ kill -9 <PID_for_root PID_for_root.exe>

I also noticed that the segfault occurs only when I change something on the canvas using the histogram editor and try to close the TBrowser after saving it.

I hope this will help you track things down. Hopefully its not some stupid mistake on my part :-p

PS: If this makes any difference, the ROOT file was generated by ATHENA 15.4.0.1 (ROOT version 5.22). It is full of TH1Fs, TH2Fs and TProfiles.

My system specifications:
2.6.30.8-64.fc11.x86_64
ROOT 5.25/03
g++ (GCC) 4.4.1 20090725 (Red Hat 4.4.1-2)

Open source is the future. It sets us free.
