Continuing the discussion from RDataFrame with Friend Tree crashes when multithreading enabled:
Are there news on this? I’m observing exactly the same behaviour, and my ROOT file also includes multiple directories.
ROOT Version: 6.18/04
Platform: slc7_amd64_gcc82
Compiler: g++ (GCC) 8.3.1 20190225
Hi @bfontana,
this sounds like https://sft.its.cern.ch/jira/browse/ROOT-10152 which was recently fixed in master (the fix will be part of v6.22/04 and v6.24).
Could you check whether a ROOT nightly build still has the issue?
Cheers,
Enrico
Hello @eguiraud,
After sourcing the nightly build as described in your link, and upon re-running the same piece of code, I still observe the same behaviour (i.e., I get a segmentation violation). The crash is avoided just by placing the ROOT::EnableImplicit call after the ROOT::RDataFrame constructor.
Hi,
too bad, I will need a reproducer then, to debug the issue.
Can you please share a (small) snippet of code that reproduces the crash and the files required to run it? You can also share the files with me privately if they cannot be made public.
Cheers,
Enrico
