We have agreed with PPD/PdmV to have a parallel build CMSSW_10_5_0_pre2_g4104p3 to test this new version vs the present setup

@civanch , by the way, last night we had built an IB ( CMSSW_10_5_GEANT104_X_2019-02-18-2300 ) with this version of geant4. Every thing looks good https://cmssdt.cern.ch/SDT/html/cmssdt-ib/#/ib/CMSSW_10_5_X for this IB. It is available for slc7_amd64_gcc700 (in case you want to run any additional tests).

@smuzaffar , thanks, a simple test is running. We with Sunanda will run also physics tests, this will need more time.
