is assert() for debug only or not?
Is it possible that I have seen the use of assert() in the Borland
c++ 32 compiler (so assert is not for debug only)?

Yes. Or let it state in another way. Assert should only be used while
the code is in development, than when you release your product/program,
you want to compile with NODEBUG defined, so that all assertions will be
gone.

It is possible, though one cannot conclude from that fact that this is
the correct usage anyway. Borland seams to have released a debug-version
or their product.

The purpose of a tool is determined by the person using it. It is
possible that someone out there uses assert() for driving nails and
uses pencils for murdering people. Is it possible that I have seen the use of assert() in the Borland
c++ 32 compiler (so assert is not for debug only)?
Is it possible that you have seen the source code of the Borland
c++ 32 compiler? I don't know. If you have, whether or not it
uses assert() says little about whether or not assert() is for debug
only. Just because code is a production release does not mean it
is bug-free. However, I'm not sure I'd be comfortable riding in
an airplane or spacecraft whose flight-control software used assert(),
or living near a nuclear reactor whose control software used it.

The most diffult to debug, to understand problems occur in once the code
is in production, where it is constantly hammerred to its limits by people
who have no respect for your test suite.
Therefore in the interest of speed, production code is precisely when
you need to disable all checking, assertions, array bounds and other
ranges, stacks popped properly, etc. This ensures the maximum damage and
the least possibility of fixing it.

as you may have gathered there are some differences of
opinion on this one. Try googling comp.lang.c for "assert".
For instance I've posted some particularly good things on
assert :-)
(google for my surname, you're unlikely to get false positives
in comp.lang.c).

It depends what your product is. If you release a game, and it assert fails,
a savvy player will know that there must be a design bug. However it is
unlikely that your studio is set up to release patches and maintenance
versions, so you end up in an awkward position.
Far better to just crash.

so that all assertions will be gone.
For amateur programmers (programmers who write code for their own use),
there is no clear distinction between
the program development phase and the program deployment phase.
They try to use their code with no formal testing
as soon as they can get it to compile without any errors.
They are always modifying and debugging their code
until they are finished using it -- then they throw it away.
For amateur programmers, it is usually sufficient
to simply exit from a program when an exception is encountered.
For professional programmers, it is almost always necessary
to include code to detect and handle the exception for users
because the users may not be programmers themselves.
The C preprocessor assert macro is almost never
the best way to detect and handle exceptions so it is not used
for exception handling by professional programmers.

The "savvy player" whose game crashes will not be keen to buy games from the
same company again.
Far better not to do things that might make the game crash.

If you're not 100% sure that the program can run correctly without the
assertions, your program is not ready for production.

In general, is it considered bad practice to use asserts in production
code?
What about writing a macro that does the same as assert but continues
to work regardless of the state of NDEBUG?
I can see that it would be poor style to use it for commonly
encountered errors, but what about truly exceptional errors that would
rarely if ever be encountered?

Besides printing out for example
" a.out: p113.c:8: main: Assertion `0' failed.

and a switch option NDEBUG, what other benefits does assert() provide
in any scope of designing, debugging/coding and/or testing?
Do you prefer the if statement of the language to the assert MACRO of
the precompiler?
