UB is a common abbreviation for "undefined behavior". The phrase
“undefined behavior” is defined by the C++ standard as having the
following meaning: “behavior for which this International Standard
imposes no requirements” (3.27). This is the most seriously negative
thing the C++ standard ever says about any C++ code. Any program that
violates at least one diagnosable rule (that term is defined in 4.1p1),
must result in the generation of at least one diagnostic message
(4.1p2). An implementation is still free to create an executable
program, and if you choose to execute it, the behavior of that program
is undefined, but at least you get that diagnostic message. When the
behavior is simply undefined, you may get no warning.  This should scare
you. If it does’t, you don’t properly understand what “no requirements”
really means.

It’s popular to explain what this means by giving a humorously
outrageous example, such as “demons may pop out of your nose” or “nasal
demons” for short. It’s fun coming up with examples, and I normally try
to give a different example every time I explain this concept. Doing so
is also useful, because the outrageusness of the example catches
people’s attention and makes it easier to remember. It’s also literally
true: there may be many reasons why it’s not possible for code with
undefined behavior to cause demons to pop out of your nose (the
non-existence of the demons being a prime example). However, a
requirement imposed by the C++ standard is NOT one of those reasons.

However, you strike me as the kind of person who wouldn’t appreciate the
humor, and would let that lack of appreciation get in the way of
correctly understanding what’s at stake. Therefore, I’ll explain the
stakes in a much more boring fashion. When you write code with undefined
behavior, you're not actually telling the implementation to do what you
think you're telling it to do - you're telling it that you don't care
what your code actually does when executed. That's something you should
avoid telling the implementation, unless it's actually true.

Is there anything, anything at all, that a program could be built to do
when run on the platform where you will be running your program, that
you absolutely don’t want your program to do? If you say “No”, there’s
no problem. There’s also no need to compile your program, or even to
write it. If you don’t care what your program does, then you can save
yourself a lot of time and trouble by using any arbitrary program you
can find that’s already been written and compiled. If you’re sane,
however, you’ll answer “Yes” to that question.

Well, when the behavior of your program is undefined, that means that a
fully conforming implementation of C++ can take your source code, and
translate it into an executable program that does whatever it is you
most strongly wish it wouldn’t do. If that statement doesn’t scare you
into avoiding undefined behavior, you really don’t understand the full
depth of “no requirements’ – none – of any sort – whatsoever.

There is an important loophole in this statement, however: it says “this
international standard”. The behavior can be undefined as far as the C++
standard is concerned, and yet there could be some document other than
the C++ standard which does impose requirements on the behavior. The
only case where you should ever tolerate C++ code with undefined
behavior is when you know three things:
1. There is a document somewhere that does guarantee the behavior of
that code.
2. That document has authority that applies everywhere that you need it
to apply.
3.   What that document guarantees about the behavior matches what you
want the behavior to be.

So – do you want to claim an exemption based upon this loophole? Then
please identify the document which provides the guarantee for the
behavior of your code which the C++ standard fails to provide, and also
identify the scope of the authority of that document, and finally
identify what precisely that document guarantees about the behavior of
your code.

I doubt that you can.
