Object does not exist after constructor?
- by openbas
Hello,
I have a constructor that looks like this (in c++):
Interpreter::Interpreter() {
tempDat == new DataObject();
tempDat->clear();
}
the constructor of dataObject does absolutely nothing, and clear does this:
bool DataObject::clear() {
//clear the object
if (current_max_id > 0) {
indexTypeLookup.clear();
intData.clear();
doubleData.clear();
current_max_id = 0;
}
}
Those members are defined as follows:
std::map<int, int> indexTypeLookup;
std::map<int, int> intData;
std::map<int, double> doubleData;
Now the strange thing is that I'm getting a segfault on tempDat-clear(); gdb says tempDat is null. How is that possible? The constructor of tempDat cannot fail, it looks like this:
DataObject::DataObject() : current_max_id(0)
{
}
I know there are probably better way's of making such a data structure, but I really like to know where this segfault problem is coming from..
