[Build] Xcode unit tests fail with libc++abi: terminating due to uncaught exception of type onnxruntime::OnnxRuntimeException:

[iOSDevD]

Describe the issue

When the unit tests are executed it fails with below exception.

libc++abi: terminating due to uncaught exception of type onnxruntime::OnnxRuntimeException: core/session/ort_env.cc:90 static void OrtEnv::Release(OrtEnv *) env_ptr == p_instance_.get() was false.

Urgency

No response

Target platform

iOS

Build script

• Open Xcode
• Create a sample unit tests
• Run the unit tests
• After the test completes it will crash with the OnnxRuntimeException

If we simply run the code on simulator all works fine, but fails only with unit tests.

Error / output

libc++abi: terminating due to uncaught exception of type onnxruntime::OnnxRuntimeException: core/session/ort_env.cc:90 static void OrtEnv::Release(OrtEnv *) env_ptr == p_instance_.get() was false.

TestFramework is the name of the XCFramework.

Looks like you have two OrtEnv instances competing with each other as the one in the call to OrtEnv::Release does not match the one inside that instance.

onnxruntime/onnxruntime/core/session/ort_env.cc

Lines 87 to 97 in 704523c

	void OrtEnv::Release(OrtEnv* env_ptr) {
	if (!env_ptr) {
	return;
	}
	std::lock_guard<std::mutex> lock(m_);
	ORT_ENFORCE(env_ptr == p_instance_.get()); // sanity check
	--ref_count_;
	if (ref_count_ == 0) {
	p_instance_.reset();
	}
	}

There should be only one OrtEnv, and it should remain valid for the duration of any inference session.

Sorry there was an error in the log, updated the logs. Thank you.
