---------------------------------------------
That's all I was told. The details were not conveyed to me, so I don't know
what kind of problems it could cause. Hence, the comment about investigating.
I'm not actually sure what strict aliasing is, or why we'd disable that
optimization, the risks/benefits of it. My guess is that an internet search
would reveal some discussion about the pros and cons about using strict
aliasing.
> Use better compiler optimizations by default for native maps

> on ACCUMULO-2749 identified improved performance with better compiler
> optimizations for native maps (-O3 instead of -O2).
> The native shared library is small, and enabling these additional
> optimizations will not result in a significantly slower build, so I don't see
> any reason why we should not enable better optimizations by default in the
> Makefile, if we can identify them.
