Memory leakage from ONNX environment on Linux machine using C.

[Krissaren]

Describe the issue

I am trying to implement models in C using onnxruntime version 1.12.0, (have also tried the newest version of onnxruntime) on a Linux machine. I face problems with memory leaks stemming from the environment creation. I have attached a part of the output from Valgrind.

The same problem i am facing in my code is appearing when trying to run the fns_candy_style_transfer example from the onnxruntime_examples. It seems to be the related to cpuinfo_x86_linux_init but i have not been able to find a fix. Any insight and help would greatly be appreciated.

To reproduce

To reproduce the issue simply compile and run the fns_candy_style_transfer example from the onnxruntime inference examples, link: (https://github.com/microsoft/onnxruntime-inference-examples/tree/main/c_cxx/fns_candy_style_transfer).

To run the example, export the path to the release of onnxruntime on your pc using command below:
export LD_LIBRARY_PATH=/path/to/your/onnxruntime/build/Linux/Release:$LD_LIBRARY_PATH

Supply the correct inputs to the script, args: input image, output image and run it using valgrind with the following arguments:
valgrind --leak-check=full --show-leak-kinds=all ./fns_candy_style_transfer model <model_path> <input_file> <output_file>

Urgency

The matter is somewhat urgent as i am trying to create a prototype to asses the feasibility in my current platform, such i can make necessary platform choices.
