This has nothing to do with Optlink.

Nor the release environment.

It is a bug either in dmd or in snn (dmc's libc).

```
fputs(("---\n" ~
     "ERROR: This is a compiler bug.\n" ~
             "Please report it via 
https://issues.dlang.org/enter_bug.cgi\n" ~
             "with, preferably, a reduced, reproducible example and the 
information below.\n" ~
     "DustMite (https://github.com/CyberShadow/DustMite/wiki) can help 
with the reduction.\n" ~
     "---\n").ptr, stream);
```

Only the first two lines are printing, as it is a CTFE concatenated 
string that is rather concerning.
