Yes: https://godbolt.org/z/d1WP4KP99

There was such an outcry when this was discovered that the C++
standard was modified to add a note explicitly allowing,
"trivial infinite loops, which cannot be removed or reordered."
https://eel.is/c++draft/intro.progress

That change is commit 29fcc1c1fab7277d96bbd2ccd37b0c14dfd75a0e
(https://github.com/cplusplus/draft/commit/29fcc1c1fab7277d96bbd2ccd37b0c14dfd75a0e)
in response to P2809:
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p2809r3.html

>and is it relevant to C?

Here's a C version with the same behavior:

```
term% cat weird.c
#include <stdio.h>

int
main(void)
{
        for (unsigned int k = 0; k != 1; k += 2)
                ;
	return 0;
}

void
hello(void)
{
        printf("Hello, World!\n");
}
term% clang --version
clang version 22.1.6
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
term% clang -Wall -pedantic -O1 -std=c23 -o weird weird.c
term% ./weird
Hello, World!
term%
```

The program above meets the criteria in sec 6.8.6.1 para 4 that
allows an implementation to assume that the loop terminates.

Regehr aluded to this with his taxonomy of undefined functions.
For a function that is always undefined (a "Type 3" function), a
compiler is under no obligation to even produce a return
instruction for it, and the behavior of a call to such a
function is totally undefined.  Nothing stops it from cascading
into whatever the linker happens to put after it.

Therefore, given UB, it is not necessary to have a reference to
some function in a program's source text in order for it to be
executed.
