when you use it wrong, you need much more memory than you actually need.

Good idea, but some options can under certain circumstances create
errors in your executable

That is very stupid. inlining very small functions that are called in
loops can be a good idea, but inlining every function in the program
is just stupid because it bloats the code which then makes code
caching very unefficient.

This can lead to errors too. be very careful.
As the foreposter said, before you start wasting your time with
useless things like spending 90% time on things that comsumes 0.01% of
performance, detect what certain loops are slow, instead of
bit-fiddling rethink your algorithms.
