In the vtkSetStringMacro there seems to be a small Bug.
When the Debug flag is on the argument _arg will be sent to the ostream. This is not bad until the macro is beeing called with _arg == NULL. This seems to be the case i.e. in the destructor of vtkXMLWriter.
The following is from Common/vtkSetGet.h :
#define vtkSetStringMacro(name) \
virtual void Set##name (const char* _arg) \
{ \
vtkDebugMacro(<< this->GetClassName() << " (" << this << "): setting " << #name " to " << _arg ); \
if ( this->name == NULL && _arg == NULL) { return;} \
if ( this->name && _arg && (!strcmp(this->name,_arg))) { return;} \
if (this->name) { delete [] this->name; } \
if (_arg) \
{ \
this->name = new char[strlen(_arg)+1]; \
strcpy(this->name,_arg); \
} \
else \
{ \
this->name = NULL; \
} \
this->Modified(); \
}
Best regards,
Roland
