cmssw: Segmentation fault in the TrackProducer for EphemeralHLTPhysics

[as current shadow ORM]

A single job was paused while processing PromptReco for the EphemeralHLTPhysics PD due to segmentation fault in the TrackProducer:

The error is locally reproducible and the job tarball (including PSet and log files) can be found here:

The simple configuration

skip_cfg.py

import FWCore.ParameterSet.Config as cms
from PSet import process


#3087                                                                                                                                                                                                       
process.source.skipEvents = cms.untracked.uint32(3086)

process.options.numberOfThreads = 1

If run in the same directory as PSet.py an PSet.pkl will fail in the first event to be processed.
