Reproduction
Take the following commit:
https://github.com/dlang/phobos/pull/5723/commits/7c47c11f8de3653b53de586bb255efa98ac8e93b

And move import core.exception/core.memory to functions in Grapheme struct
where they are used.

Build Phobos tests.

Interestingly debug version links fine.

The release unittest runner does not:
