Description

The module InputCppRootData can cause an error due to an overflow in the maximum number of reference counts if it is used to import a data file of significant size. Output:

TRANSFORM/MERGE/OUTPUT:  Processed 97 events so far, 1 events in buffer.
terminate called after throwing an instance of 'MAUS::Exception'
  what():  Too many data references at Data::IncreaseRefCount
Aborted

This arises from the IncreaseRefCount method of the Data datastructure class. Looks like a buffer needs flushing somewhere.

I could not reproduce the bug. I attempted to load 1000 spills successfully. Download attached tarball, untar then do

bash run.bash

Any clues?

I am waiting for a response - I can't reproduce the bug, so can't fix it! A little help please?

Hi Chris, sorry, somehow didn't receive an email notification from post #1.
I've attached a set of scripts that reproduce the error. Adjust the paths, then run dstest.sh
