hello,

some rtt tests failing due to a seg fault during muoncombinedrefit
caused by trk::globalchi2fitter::backupcombinationstrategy

you can find a log file here:
https://atlasrtt.cern.ch/rtt_j_r/rel_2/devval/build/i686-slc5-gcc43-opt/offline/recperftests/all_bs/all_bs_log

and a script to run the test:
https://atlasrtt.cern.ch/rtt_j_r/rel_2/devval/build/i686-slc5-gcc43-opt/offline/recperftests/all_bs/runscript.sh

please take a look.

thanks,
felix friedrich [sw-val shifter]
