Yes. It seems that problem. However, I get into another problem.

SUMMARY: AddressSanitizer: double-free
(/usr/lib/x86_64-linux-gnu/libasan.so.3+0xc8630) in operator delete(void*)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
In summary,
std::vector<of10::PacketOut>
vec_packet_out=feature_response_process(std::move(featuresReply));
Within feature_response_process(), I create PacketOut one by one (within
for loop) and add into vector.
PacketOutCommon::~PacketOutCommon() {
if (this->data_len_) {
::operator delete(this->data_);
}
}
As shown in line 307, ::operator delete(this->data_); In my understanding,
vector keeps copy of PacketOut.
My question is that why this error comes?
Thanks again.
