The general scheme is probably common: unresolved expr -> ??? -> an expression is dependent but not marked as such -> constant evaluation crashes.

But the ??? matters, as that's where the fix is.
In the case above: expr is used in a member of X, and X is not a dependent type, so sizeof(X) is not considered dependent
