> I found this when building the kudu/util subtree in Impala with gcc 7.1.
> In a few places, e.g. metrics.h, the compiler complains that the alignment required by Counter is less than the alignment guaranteed by new.
> {code}
>     m = new Counter(proto);
> {code}
> I worked around this by setting -faligned-new, which was added recently to GCC and is enabled by default with C++17. The setting ensures that new allocates memory with the alignment required by the data type.
