[Rivet] Segfault with two analyses

[Thomas Gillam]

Hi,

I'm using Rivet v1.7.0 as a means to process signal monte-carlo for a susy search. I've been using slightly modified versions of ATLAS_2011_CONF_2011_090 and ATLAS_2012_I1083318 (to add more histograms), with events generated by Herwig++.

Each analysis runs fine individually, however when running together Rivet segfaults at some point in the run of 10000 events. The segfault does not always occur in the same place - in particular, I've tried running in pdb, and the segfault did not occur at all. Could this be some kind of race condition?

Do you know what might be causing the issue, or anything I could do to get to the bottom of it please? I don't have much experience with Rivet, so it's entirely possible I'm setting it up incorrectly...

Many thanks, and best wishes,
Tom
