@SixthDot created dlang/dmd pull request #15699 "fix issue 4541 - linker
failure due to AddrExp on intrinsic function" fixing this issue:

- fix issue 4541 - linker failure due to AddrExp on intrinsic function

  The expression results now in a semantic-time error,
  which is the only simple solution.

  DMD Intrinsics map to libc functions, which can give the impression
  that taking the address is possible, but more generally an intrinsic
  can also have for effect to insert platform-specific instructions,
  as seen in LLVM.

@Walter: Did you read the comments ?

The test case nowadays is:
```
import core.math;
void main() {
real function(real) c = 
}
```

And it still fails:
```
test.o: In function `_Dmain':
test.d:(.text._Dmain[_Dmain]+0x7): undefined reference to
`_D4core4math3sinFNaNbNiNfeZe'
collect2: error: ld returned 1 exit status
Error: linker exited with status 1
```

Tested with both 2.076.1 and HEAD (51bc2fb42)

It works fine when I try it with the latest.

Relying on user knowing of internal details is not a solution. Moreover, this
doesn't take into account generic code. If one write a template that accept a
static function via a template this argument, do you really expect this person
to handle the case of someone passing an intrinsic explicitly ?

Intrinsics shouldn't differ from regular functions.

The correct course of action would be to properly tag the bug as being within
DMD.

I think that this issue is no longer valid since using the std.math wrappers
results in successful compilation. Even though using core.math results in link
failure, I do not think this is a problem since that is the runtime library and
who uses it should know that the functions declared there are intrinsics.
Anyway, this is not a phobos bug anymore and I don't think it is a druntime one
either. Closing
as fixed.

intrinsic have been moved to `core.math` and `std.math` nowadays (since 2.069 /
https://github.com/dlang/phobos/pull/3599 ) provide wrappers around it to
mitigate the issue.

In order to reproduce this, one can use:

import core.math;
void main() {
real function(real) c = 
}

instead of the op's code.

Perhaps a possible workaround is to have the compiler emit a wrapper function
when the address of an intrinsic is asked for, and return the pointer to the
wrapper?
