[FastRTPS/FastDDS] reader->type().delete_data(data) in callbacks causes segfault #4

Closed fpedd closed 3 years ago

fpedd commented 4 years ago

In void Listener::on_data_available(DataReader* reader) we create void* data = reader->type().create_data();. However, when trying to reader->type().delete_data(data); we get a segfault. Therefore it is commented out for now and marked with TODO. For now not deleting data does not cause any negative side effects.

Did you check if data pointer is created and not NIL?

Issue closed since no reader void *data = reader->type().create_data(); is used anymore. However, the problem arises if reader will be deleted even if data is empty.
