Hi Guomin,

Thanks for point the commit below to me. I agree that the change is functionally the same, and I am also with Sean that the local variable seems redundant. But is there other reason we used this local variable in the first place? I thought the first implementation<https://github.com/microsoft/mu_basecore/blob/608b28d6e2b977dfb05d806bf4d1c4fd12c87462/MsUnitTestPkg/Library/UnitTestLib/UnitTestLib.c#L263> did not have it.

Thanks,
Kun

Hi Sean,

I think it meet the original code logic more closely.

According to the LoadUnitTestCache(), it need pointer to pointer, the defect is resulted by pointer to local pointer and I think the original logical just want use the local variable as pointer to pointer.

I have reviewed the suggested change and think both are the same logic.

Hi Qin,

Can you give some comment?

Best Regards

Guomin,

Can you speak to why you implemented differently than the suggested and validated patch?  Seems you created a local whereas ours just used the internal data member.

Thanks
sean
