Package: libarts1
Version: 1.1.1-2
Artsd SEGV on executing any example module of the artsbuilder. According to gdb at: 

/usr/include/kde/arts/dynamicskeleton.h line 116:
class DynamicSkeleton : virtual public Parent_skel, public DynamicSkeletonBase 
{
public:
       /**
        * constructor
        */
       DynamicSkeleton(const std::string& interface)
: DynamicSkeletonBase(this, interface, Parent_skel::_interfaceNameSkel()) 
       {
               //
       }
...
It was called by SynthModule_dskel(structureDesc.name()) in the Structure_impl constructor.
It rarely got through the constructor DynamicSkeletonBase::DynamicSkeletonBase(Object_skel *skel, const std::string& interfaceName, const std::string& interfaceNameParent)
The suspect is the interfaceNameParent reference in the constructor. It is defined as const std::string&. If we look at mcop/artsflow.cc generated by the mcopidl, we are eventually calling methods like this: 

std::string Arts::SynthModule_skel::_interfaceNameSkel()
{
       return "Arts::SynthModule";
}

It is the same for all other modules.
On a test program and g++-3.2.3, it would warn us about "returning reference to temporary" on compilation. The exec would SEGVwhen we make use of the return. 

Regards.
