nikic added a comment. At least in C++, working with uninitialized memory is pretty much always immediate undefined behavior, see https://eel.is/c++draft/basic.indet for the relevant wording. The only exception are "copy-like" operations on unsigned character types, which comparisons do not fall under.
I believe the C specification is less clear cut about this, but Clang and LLVM assume basically the same to also hold for C code.
