hi mark,

atn tests show, there's a fpe in every event:
fpeauditor        warning fpe overflow in [execute] of [cbntaa_eflow]

see e.g. 
http://atlas-computing.web.cern.ch/atlas-computing/links/distdirectory/nightlies/developmentwebarea/nicos_web_area170xval32bs5g4recopt/nicos_testlog_rel_2/reconstruction_recexample_recexcommon___recexcommon_testconfiguration__recoshift_recexcommon_warning_and_error__m.html

could you fix this, please ?

thanks, rolf
