Hi @bsunanda , Can you provide a simple reproducer of your case? Together with some information about your system (how you installed ROOT etc., compiler version etc.)

pcanal commented 1 year ago

Alternatively you can run valgrind to get more information on this kind of failure:

valgrind --suppressions=$ROOTSYS/etc/valgrind-root.supp --log-file=val.01.log myexecutable myargs

Thanks Philippe - I shall try that

Dear Philippe

Sorry for late response. The crash depends on the input file. I landed with one file and here is the log file which came from running valgrind. I cannot find out the real reason from this. Could you point out where I should look into this?? Thanks and regards

Sunanda

here is the log file which came from running valgrind

I don't find this; could you attach it at https://github.com/root-project/root/issues/12370 please?

The crash depends on the input file. I landed with one file and here is the log file which came from running valgrind.

Does the crash with valgrind have the same symptoms as the original problem (i.e. seg fault in TStreamerInfoActions::VectorLooper::ReadCollectionBool)?
