You can try to add the flag `--disable-verify` (see 
https://github.com/ldc-developers/ldc/issues/4284, that prevents 
an internal verification).

The error message indicates that a "parameter-only" attribute is 
used as a "call-site" one. Not sure if this is a bug in LDC or in 
LLVM but if you're lucky the attribute will be a no-op and the 
generated binary will just work.
