Bug #17255

Updated by Gianluca Petrillo over 2 years ago

In trying to run single particle simulations in the context of ICARUS I encountered an exception that stops processing when running the Geant4 step. The messages are:
<pre>%MSG-d


%MSG-d
ParticleListAction::SteppingAction: LArG4:largeant@ 21-Jul-2017 11:24:42 PDT run: 1 subRun: 0 event: 1 ParticleListAction.cxx:350
: DEBUG - process='muIoni' ignoreProcess=0 fstoreTrajectories=1
%MSG
ERROR: 8 - Floating point inexact result.

Abort trap: 6</pre> 6

This is using a debug build on OS X (Yosemite) in larsoft @v06_44_00@ v06_44_00 and with the current develop branch of @icaruscode@. icaruscode.
Steps to repeat:
# 1) first one should generate some number of particles:
<pre>lar

lar
-c prod_muon_0-1GeV_isotropic_icarus.fcl -n 100</pre>
#
100

2)
With this output file, run the geant4 step:
<pre>lar

lar
-c standard_g4_icarus.fcl -s prod_mxxxxx -n 100</pre> 100
