Onnxruntime with extension has memory leak in EnableOrtCustomOps()

OS:

Ubuntu 20.04/16.04

Onnxruntime version:

1.12.1

Hi, I'm getting memory leak with ASAN build when enabling custom Ops. I haven't seen any updates in 1.13.1 release notes so I assume this leak is still there.
The code is straightforward. Any help would be appreciated on how to release the memory properly:

m_sessionOptions.SetIntraOpNumThreads(m_modelThreads);
m_sessionOptions.SetGraphOptimizationLevel(GraphOptimizationLevel::ORT_ENABLE_ALL);
m_sessionOptions.DisableCpuMemArena();

m_sessionOptions.EnableOrtCustomOps();
m_modelSession = Ort::Session(m_env, modelFile.c_str(), m_sessionOptions);

Here's the 2 leaks:
