> Project: IMPALA

> Priority: Minor
> Fix For: Impala 4.0

>
> Google test uses a macro to avoid a GCC warning about dangling else
> conditions. It suppresses a warning for code like:
> {code:java}
> if (foo) DCHECK(condition);{code}
> [https://github.com/google/googletest/issues/1119]
> GCC 7 added new warnings and this macro no longer works. The solution is to
> either disable the new warning or use braces. Since using braces is easy, we
> should fix this by adding appropriate braces.
