There are two options: - WITH_INIT_ALL_ZERO: Zero all variables on the stack. - WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns. The exact pattern are a compiler implementation detail and vary by type. They are somewhat documented in the LLVM commit message: https://reviews.llvm.org/rL349442 I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather than naming them after the LLVM specific compiler flags. In a range of consumer products, options like these are used in both debug and production builds with debugs builds using patterns (intended to provoke crashes on use of uninitialized values) and production using zeros (deemed more likely to lead to harmless misbehavior or NULL-pointer dereferences).
