? It's outputted when building and running a test application
with ldc with the compiler flag `-fsanitize=address`.
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.
