Mike, can you, please, re-check if 10.4 has the problem. It should disappear. Cheers, Vladimir (In reply to Vladimir.Ivantchenko from comment #1) > can you, please, re-check if 10.4 has the problem. It should disappear. Hi, Vladimir. This specific message (G4Material => G4IonisParamMat leaks) is gone in 10.4. However, there are several new leak messages coming from a variety of places in the physics list (mostly hadronics). I think this bug report can be closed. -- Mike Kelsey |
Running Valgrind (--tool=memcheck) generates a report when the "derived material" construction is used, for example to create a new material with a different density than one which is already defined. My code for this looks like: // Kapton tape, used for striplines (data from NIST) // Cirlex, bulk Kapton, used for circuit boards void CDMSMaterialTable::CreateKapton() { G4Material* kapton = new G4Material("Kapton", 1.42*g/cm3, 4); kapton->AddElement(nist->FindOrBuildElement("H"), 0.026362); kapton->AddElement(nist->FindOrBuildElement("C"), 0.691133); kapton->AddElement(nist->FindOrBuildElement("N"), 0.073270); kapton->AddElement(nist->FindOrBuildElement("O"), 0.209235); new G4Material("Cirlex", kapton->GetDensity(), kapton); } In Valgrind, this produces six reports, all essentially identical (only the pointer locations of "nearbyint" differ): ==4808== Conditional jump or move depends on uninitialised value(s) ==4808== at 0x107459830: nearbyint$fenv_access_off (in /usr/lib/system/libsystem_m.dylib) ==4808== by 0x1043D96BE: G4IonisParamMat::G4IonisParamMat(G4Material*) (in /Applications/GEANT4/geant4.10.02-seq/lib/libG4materials.dylib) ==4808== by 0x1043E300C: G4Material::CopyPointersOfBaseMaterial() (in /Applications/GEANT4/geant4.10.02-seq/lib/libG4materials.dylib) ==4808== by 0x1043E2E33: G4Material::G4Material(G4String const&, double, G4Material const*, G4State, double, double) (in /Applications/GEANT4/geant4.10.02-seq/lib/libG4materials.dylib) ==4808== by 0x10038C242: CDMSMaterialTable::CreateKapton() (CDMSMaterialTable.cc:228) ==4808== by 0x10038A8D2: CDMSMaterialTable::CDMSMaterialTable() (CDMSMaterialTable.cc:112) ==4808== by 0x10038A084: CDMSMaterialTable::CDMSMaterialTable() (CDMSMaterialTable.cc:83) ==4808== by 0x10038A02A: CDMSMaterialTable::Instance() (CDMSMaterialTable.cc:75) ==4808== by 0x10006B4D0: CDMSGeomConstructor::CDMSGeomConstructor() (CDMSGeomConstructor.cc:147) ==4808== by 0x10006B674: CDMSGeomConstructor::CDMSGeomConstructor() (CDMSGeomConstructor.cc:144) ==4808== by 0x100001BEE: SuperSim_Main::Configure(G4String const&) (SuperSim_Main.cc:85) ==4808== by 0x1000013DF: main (CDMS_SimDraw.cc:20) This is present in 10.2 and 10.3, and probably earlier releases as well.
