Hi,

I tried to update my server from dmd v2.096.1 to v2.097 and I 
started getting this linker error:

```
Linking...

collect2: error: ld returned 1 exit status
Error: linker exited with status 1
/usr/bin/dmd failed with exit code 1.
```

What's the best aproach on debugging linker errors with DMD on 
linux?


Best,
Bogdan

I'd try the following options

- `--force` dub to rebuild everything.
- `-allinst` in the dflags.
- `-verbose` output can show interesting details sometimes.
- the different linking mode proposed by dub.

if one of te following fixes the issue then maybe that digger can 
help to detect a regression.
