Description Andrea Dotti 2014-04-10 19:35:13 CEST 
In MT mode the following UI commands cause a crash:
/physics_engine/tailor/SyncRadiation on
/physics_engine/tailor/MuonNuclear on
The following exception is issued:
-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : Run11002
       issued by : G4WorkerRunManagerKernel::SetupShadowProcess()
  Size of G4ProcessVector is inconsistent between master and worker threads
for the particle <e+>.
  size of G4ProcessVector for worker thread is 9 while masther thread is 10.
*** Fatal Exception *** core dump ***
-------- EEEE -------- G4Exception-END --------- EEEE -------

The problem being that the messenger exists only for master thread. Thus command has no effect in worker and wrong physics status is produced.

Problem identified. I am working on that. It will require a tag in physics list.
Since I do understand now the problem, I will go through all physics constructors and verify if similar problems are present in other areas.
