Problem 1244

Summary:	Constructor of G4MaterialPropertyVector leaves uninitialized variables
Product:	Geant4	Reporter:	David Jaffe <djaffe>

Description David Jaffe 2011-08-24 21:02:13 CEST

If the constructor,
	
	G4MaterialPropertyVector(G4double *PhotonEnergies, 
		  	   	 G4double *PropertyValues,
				 G4int     NumElements);

is used, then the Last... variables that are normally initialized with the other constructor,

	G4MaterialPropertyVector() : MPV(0) 
	{
		CurrentEntry = -1;
		NumEntries   = 0;
		LastRequestedPhotonEnergy = -1;
		LastReturnedValue = 0;
	};

are left uninitialized. The latter constructor is used by GiGa.

Hi David,

What version of Geant4 are you using? The variables LastRequestedPhotonEnergy and  LastReturnedValue do not look familiar to me? Can it be that you are using a GiGa modified version?

Cheers, Peter

Hi Peter,

 We have indeed applied a patch to Geant4.9.2.p01's G4MaterialPropertyVector, so this is not a G4 bug.

 My apologies!
