What is the Strict Aliasing Rule and Why do we care?

(OR Type Punning, Undefined Behavior and Alignment, Oh My!)

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th

# This CMake file will build Freetype and Harfbuzz as external

# https://sourceforge.net/projects/freetype/files/freetype2/2.5.3/ So,
# first we build Freetype2 w/o Harfbuzz, then we build Harfbuzz with
# freetype support after which we rebuild Freetype2 again.
#
# Both CMake files of Freetype2 and Harfbuzz are depending on
# pkg-config to find the dependencies for both projects. I've
