Thanks for the tip, indeed it was caused by `ld` picking up the 
wrong lib (in a different sys path):

```
$ locate libdruntime-ldc
(... my local LDC install)
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-debug-shared.so
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-debug-shared.so.2.0.98
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-debug-shared.so.98
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-debug.a
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-shared.so
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-shared.so.2.0.98
/usr/lib/x86_64-linux-gnu/libdruntime-ldc-shared.so.98
/usr/lib/x86_64-linux-gnu/libdruntime-ldc.a
```

while I'm using my local installed LDC.  After removing the 
system installation, it worked.
