Description

Hey, I'm not sure if this is the right place to post this issue. It may be an issue with mono itself. Please close this if it is unrelated to this project.

You can reproduce the issue like so:

public enum TestEnum {
	A, 
	B, 
	C, 
};

{
	TestEnum test = TestEnum.B;
	Debug.LogWarning(test);
}
{
	TestEnum test = TestEnum.C;
	Debug.LogWarning(test);
}

When putting a breakpoint on the second test and reading its value, a value of B will be reported, when the correct value is C.

Research direction
