The question is titled "Easy way [to] find uninitialized member variables". These are not member variables. We all know about -Wunitialized for non-member variables, and we should all have it already as part of already using -Wall -Wextra -Wpedantic. Also, it does not "need the -O3 option" or any other form of optimisation to be present or absent, although they may affect which warnings are returned if optimisation causes side-effect-less variables to be removed.
