Since commit 5d12b13b0b26bc58b02ee23c369da8b83240cceb, warnings are internally classified as errors which skip the check filters. One use-case is particularly affected: you cannot selectively disable clang-analyzer-core checks, they are force-enabled because required by others. So enabling warning as errors will show new (and unwanted) errors !
