in nightly 16.6.x-val, the following rtt jobs are crashing due to memory allocation problems after a call to *trigtrt_trackextensiontool::m_preloadrobs(trigindettrackcollection**):

  - job *pu_mu230.0_wtrigtruth*

the *full logfile* can be found [https://atlasrtt.cern.ch/rtt/rel_4/16.6.x-val/build/i686-slc5-gcc43-opt/offline/recjobtransformtests/pu_mu230.0_wtrigtruth/pu_mu230.0_wtrigtruth_log here].
