-------------------------------------
Summary: Fix GCC 7 compilation issue: Ambiguous else warning with
gtest macros
Key: IMPALA-9761
URL: https://issues.apache.org/jira/browse/IMPALA-9761
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 4.0
Reporter: Joe McDonnell
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.
