>                 Key: IMPALA-3675
>                 URL: https://issues.apache.org/jira/browse/IMPALA-3675
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Backend
>    Affects Versions: Impala 2.6.0
>            Reporter: Silvius Rus
>            Priority: Minor
>              Labels: newbie, static-analysis
>
> Currently it seems we're only using -Werror with debug builds.
> The problem is that a number of GCC warnings get issued by the analysis/transformation at -O2 or higher.  So there could be warnings in our release builds that we're simply ignoring.
> We should consider turning -Werror on in release builds.  Perhaps have another "static-analysis" target that does something like this (and use it in GVMs and recommend before submitting code reviews):
> {code}
> g++ ${CXX_FLAGS_RELEASE} -fsyntax-only -Werror -Wfatal-errors ...
> {code}
