Christopher Tubbs resolved ACCUMULO-2762.
-----------------------------------------
Resolution: Fixed
Okay. Re-closing this. It seems like it should be fine for us to not exclude
this optimization, based on the following assumptions:
# Our native code is small, depending mostly on STL stuffs, and we don't do
crazy stuff that risks these sorts of bugs.
# Risk of buggy code is small, because the code paths are thoroughly exercised
and we'd catch them in testing.
# If this optimization does cause problems due to buggy code, we'd rather fix
the bug rather than avoid the optimization.
> 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.
