"de-facto" means it is /not/ guaranteed !

The code you showed would not compile with the compiler and flags that I
use.  It is not a matter of it might generate unexpected code - it is a
matter of failing to compile.

And the flags I use here are not particularly unusual amongst people who
care about code quality:

	gcc -O2 -Wall -Werror

Guess what the fatal error message is?

"""
error: dereferencing type-punned pointer will break strict-aliasing
rules [-Werror=strict-aliasing]
"""

Oh, in fact it /does/ have a something to do with the aliasing options
of the compiler.  The error comes because the compiler, with -O2,
enables the "-fstrict-aliasing" option - it assumes you understand the C
and C++ rules here, and optimises your code on that assumption.


It is, of course, my choice to use the compiler in a way that minimises
the risk of accidentally writing incorrect code.  And if code quality is
not an issue for you, then you can write whatever you want and turn off
or ignore any warnings you get.  But this is an example of a commonly
used C++ implementation which fails to support the code you wrote.

The compiler I use doesn't ignore it - with the options I use, it
rejects it (this is entirely compliant with the standards - a compiler
does not have to accept code with undefined behaviour).  It also
provides an option (-fno-strict-aliasing) to let people write code like
yours if they want.  I agree, compiler vendors should not ignore
mistakes like this, and good compiler vendors do not ignore it.

Bad compiler vendors quietly accept it, encouraging people to mistakenly
think their code is fine.

Again, you are wrong.

The principle - that you may not use inappropriate lvalue types for
accessing data - is independent of what the compiler may know or not
know.  This is because the language does not specify what the compiler
may or may not know.  In some compilers, the compiler looks only at an
expression at a time, and knows very little - in others, there is whole
program optimisation allowing it to know aliasing information across units.

That is why breaking these aliasing rules is undefined behaviour, and
not a constraint (which would require the compiler to give a diagnostic)
- compilers can, and should, issue a diagnostic if they can see
unavoidable undefined behaviour, but the standards don't insist that
compilers are that smart.
