Segfault in PrStoreUTHit
A segfault occurs when running standalone_hlt2_reco without the GEC on a recent MC production: /lhcb/MC/Upgrade/XDIGI/00125245/0000/00125245_00000068_1.xdigi. It can be reproduced with:
lb-run --nightly lhcb-head Moore/HEAD gaudirun.py moore_options.pywhere a simple moore_options.py can be found here and the xdigi file has to be downloaded to the working directory. Note the problematic event is after event 921, so the first 900 are skipped in these options.
