--- Comment #21 from Carlos Galvez <carlosgalvezp at gmail dot com> --- > Why are you using the attribute at -O0? We typically run our sanitizer builds at -O0 to ensure no UB is optimized away before the sanitizer gets a chance to detect it. Is there a more suitable optimization level for sanitizer? I can also mention the problematic code is not ours, but as good practice we aim to build all source code (internal and external) with the same flags.
