Hi
First，I introduce the installtion of mongo-cxx.My centos has gcc4.8.2 and gcc4.4.6, but I install the boost1.55 and mongo-cxx with gcc4.8.2. And it's fine.
I have a function to get query results and push them into a vector(vec). But when I get the data from the vec, segment fault occurs. code is :
cursor = conn->query(dbco , obj);
vector<BSONObj> vObj;
while(cursor->more()){
vObj.push_back(cursor->next());
}
BSONObj temp = vObj[0];// vObj.size()>0
cout << temp.objsize()<<endl;
gdb debug info is :
(gdb) bt #0 0x00007ffff6432e36 in ?? () #1 0x000000000040b460 in mongo::ConstDataView const& mongo::ConstDataView::readNative<int>(int*, unsigned long) const () #2 0x000000000040a491 in int mongo::ConstDataView::readNative<int>(unsigned long) const () #3 0x0000000000409627 in int mongo::ConstDataView::readLE<int>(unsigned long) const () #4 0x0000000000408d3d in mongo::BSONObj::objsize() const ()
anyone know this?
the some code is fine with my mac.
