It is not just debug info. Read my reasons carefully - debug options may 
insert code for bounds check, initialize malloc memory etc.

It would be easy to check if -g has an impact on performance. Just 
generate a bintray build with just "-O3" and we can run a quick 
benchmark to check if there is any significant impact on the 
performance. This will give us hard data to make a decision. If there is 
no impact, then your may revert to status quo.
