Description

This PR: https://github.com/dlang/druntime/pull/3701

Has a link failure when compiling the following test:
```
void test8765(string msg, int a)
{
    assert(a);
    assert(msg == "0 != true");
}
```

When compiling with the flags: dmd testassert.d -checkaction=context -main

Bisecting druntime, this is caused by https://github.com/dlang/druntime/pull/3493
Bisecting dmd is still underway.

Can only go as far back as the following PR in dmd before druntime no longer is compilable.

https://github.com/dlang/dmd/pull/12209

Fair amount of reduction needs to be done.

Currently `-checkaction=context` is not usable without `-unittest`, at least this has been our experience. It results in heaps of undefined symbols.

This is due, I believe, to Druntime being compiled with `-checkaction=D` (the default).

Both `-checkaction=D` and `-release` (or `-check=assert=off`) prevent the message generation.
