For me, COMPILE_TEST is for compiling test without the related hardware supports, but the code should no any logical issues firstly (at least, COMPILE_TEST itself should not generate additional logical bugs).
In our case, I guess the first 2 issues are about logical issues (not hardware supporting issues), so I guess, it is not suitable to use COMPILE_TEST to bypass them.
