Hello Carsten and Gerrit, I have not solved this issue yet but I have a little peace of extra information.
The crash happens in void ShaderValueVariable::changed(ConstFieldMaskArg whichField, UInt32 origin, BitVector details) { MFParentFieldContainerPtr::const_iterator parentsIt = this->_mfExeParents.begin(); MFParentFieldContainerPtr::const_iterator parentsEnd = this->_mfExeParents.end(); MFUInt16::const_iterator idxIt = _mfExeVariableIdx.begin(); OSG_ASSERT(_mfExeParents.size() == _mfExeVariableIdx.size()); while(parentsIt != parentsEnd) { -> (*parentsIt)->changed( TypeTraits<BitVector>::One << parentsIt.getParentFieldPos(), ChangedOrigin::Child, *idxIt); ++parentsIt; ++idxIt; } ... because the _mfExeParents does contain garbage. Now I have looked up the place where this container is filled. This is done in void ShaderProgramVariables::merge(ShaderProgramVariables *pVars, MFInt32 *pVarLoc, MFInt32 *pProcVarLoc) { ... for(; vIt != vEnd; ++vIt) { if(*vIt != NULL) { -> (*vIt)->addExeParent(this, ShaderProgramVariables::VariablesFieldId, uiPos); ... However, I could not find any call to the corresponding subExeParent function nor to any other appropriate cleanup method. void ShaderValueVariable::addExeParent(FieldContainer * const pParent, UInt16 uiParentFieldId, UInt16 uiVarIdx ) { editMField(ExeParentsFieldMask, _mfExeParents ); editMField(ExeVariableIdxFieldMask, _mfExeVariableIdx); _mfExeParents .push_back(pParent, uiParentFieldId); _mfExeVariableIdx.push_back(uiVarIdx ); } void ShaderValueVariable::subExeParent(FieldContainer * const pParent) { Int32 iParentIdx = _mfExeParents.findIndex(pParent); if(iParentIdx != -1) { editMField(ExeParentsFieldMask, _mfExeParents ); editMField(ExeVariableIdxFieldMask, _mfExeVariableIdx); _mfExeParents .erase(iParentIdx); _mfExeVariableIdx.erase(iParentIdx); } } Maybe this is of some help. Currently, I'm not in the position to solve this issue.
