================ Comment at: lldb/source/Plugins/Process/scripted/ScriptedProcess.cpp:332 + lldb::ThreadSP thread_sp = + std::make_shared<ScriptedThread>(*this, error, *val->GetAsGeneric()); + ---------------- @labath This is why I switched to a raw pointer in D117065. Basically, I fetch a python dictionary for the `thread_info_sp`. It gets converted to a `StructuredData::Dictionary` and every element gets re-allocated in `pythonObject::CreateStructuredDictionary`. Then I iterate over each of element of the StructuredData::Dictionary and passes the StructuredData::Object to the ScriptedThread constructor. The ScriptedThread needs a valid reference to the python object instance to perform calls on it. However, when the structured dictionary goes out of scope (at the end of the function), all the objects it holds get destroyed so when the ScriptedThread tries to make a call on the python object is causes a heap-use-after-free.
