there is a crash in the package 
reconstruction_recexample_recexanatest 
in 
recexanatest_testconfiguration#recoshift_all
that shows up in rel_5 in the x86_64 build of 17.0.x but not in the i686 one. it seems to be due to antikt4towerjetsfixit. i had not reported it earlier because i had confused it with the other bug with antikt4truthjetsfixit (#82070). probably the problem is similar?
